Suunto Race 2 and Vertical 2 leak in full, revealing new heart rate sensor and chip

The leak didn’t arrive as a vague certification filing or a single blurry product shot. What surfaced is effectively a full hardware and feature rundown for both the Suunto Race 2 and Suunto Vertical 2, detailed enough to map exactly where Suunto is pushing forward and where it is clearly iterating.

For performance-focused users, this matters because the changes aren’t cosmetic. The leaked specifications point to a new optical heart rate sensor stack, an updated silicon platform, and subtle but important refinements to GNSS, battery management, and display behavior. Taken together, they outline Suunto’s clearest attempt yet to close long-standing gaps versus Garmin’s latest Elevate Gen 5 hardware and COROS’ increasingly efficient GPS platforms.

What follows is a clean, side-by-side look at what the leak actually confirms for each watch, with interpretation clearly separated from speculation, and with an eye on how these specs translate to real training and outdoor use rather than marketing bullet points.

Suunto Race 2: Leaked Core Hardware and Build Details

According to the leak, Suunto Race 2 retains the same fundamental design language as the current Race, including the AMOLED display and crown-based navigation, but nearly everything underneath that screen has been revised.

Display size and resolution appear unchanged, maintaining the bright, high-contrast AMOLED panel that already set the Race apart from the Vertical in everyday visibility and indoor training. The glass remains sapphire, and the case material is still listed as stainless steel, suggesting Suunto is prioritizing durability and perceived quality over weight savings in this line.

Weight is reported to be marginally reduced, likely through internal layout optimization rather than material changes. For runners, this suggests better long-term comfort without compromising the solid feel that distinguishes the Race from lighter polymer-based rivals.

New Optical Heart Rate Sensor: The Most Meaningful Upgrade

Both the Race 2 and Vertical 2 are listed with an all-new Suunto optical heart rate sensor module, replacing the previous generation unit that has been a consistent weak point in wrist-based accuracy during intervals and trail running.

The leaked diagrams and spec notes suggest a multi-LED, multi-wavelength layout, likely adding additional green emitters and possibly a red or infrared channel. This mirrors the industry-wide move seen in Garmin Elevate Gen 5 and Apple’s latest sensor stacks, where more LEDs and improved photodiode placement significantly reduce cadence lock and signal dropout.

If the leak is accurate, this would be Suunto’s first real attempt to match competitors not just on steady-state heart rate, but on high-variance efforts like hill repeats, fartlek sessions, and technical trail descents where arm movement spikes. Chest strap support remains unchanged, but the implication is that fewer users will feel forced to rely on one.

Updated Chipset and Performance Platform

The most consequential internal change is the move to a new wearable chipset platform across both models. While the leak does not name the silicon vendor explicitly, multiple references point to a newer, more power-efficient MCU with improved sensor fusion and display handling.

Practically, this should translate into faster UI responsiveness, shorter lag when scrolling maps or data screens, and more stable performance when logging long activities with navigation enabled. This is an area where Suunto has historically trailed Garmin, particularly on complex routes with dense breadcrumb tracks.

There are also hints of improved co-processor handling for sensor data, which would explain how Suunto plans to run a more demanding heart rate sensor without sacrificing battery life.

GNSS and Navigation: Incremental but Important Refinements

Both watches are listed with multi-band GNSS support, including dual-frequency reception for GPS, Galileo, GLONASS, and BeiDou. This is not new in isolation, but the leak notes revised antenna tuning and firmware-level improvements to track smoothing.

For trail runners and mountain athletes, this suggests better positional stability in narrow valleys, dense forest, and urban canyons. It is unlikely to leapfrog Garmin’s latest multi-band implementations outright, but it signals that Suunto is no longer content with “good enough” GPS accuracy.

Offline maps remain a core strength, with the Vertical 2 continuing to emphasize large-area map storage and solar-assisted endurance.

Battery Life Claims: Efficiency Over Raw Capacity

Battery capacity figures appear largely unchanged, but estimated endurance numbers show small gains across all activity modes. This points to efficiency improvements driven by the new chipset and refined sensor duty cycling rather than larger batteries.

The Race 2 is listed with slightly improved AMOLED-on endurance during GPS activities, addressing one of the original Race’s biggest trade-offs. The Vertical 2 continues to dominate on ultra-long expedition modes, especially in the solar variant, reinforcing its positioning for multi-day adventures rather than daily smartwatch use.

Charging hardware and connectors remain the same, which will be welcome news for existing Suunto users with multiple devices.

Software, Compatibility, and Daily Usability

From a software standpoint, the leak shows no radical UI overhaul, but several under-the-hood updates tied to the new hardware. Faster sync times, smoother map panning, and more responsive widgets are explicitly mentioned.

Platform compatibility remains unchanged, with full support for both iOS and Android via the Suunto app. There is no indication of onboard music or LTE, reinforcing Suunto’s focus on pure training and outdoor performance rather than lifestyle features.

Comfort-related details, including strap width and lug compatibility, appear unchanged, meaning existing accessories should carry over seamlessly.

How This Positions Suunto Against Garmin and COROS

Taken as a whole, the leaked specifications suggest Suunto is finally addressing its two most persistent criticisms: wrist heart rate accuracy and processing performance. Neither the Race 2 nor the Vertical 2 looks like a revolutionary reinvention, but both appear to close meaningful gaps that previously pushed serious athletes toward Garmin or COROS.

If the new heart rate sensor performs anywhere near its rivals in real-world testing, and if the chipset delivers the promised responsiveness, these watches would represent Suunto’s strongest competitive hardware generation in years. The leak doesn’t promise dominance, but it does point to parity in areas that matter most when training gets hard, long, or technical.

The New Optical Heart Rate Sensor: What’s Changed and Why It Matters

If the chipset upgrade is about speed and efficiency, the optical heart rate sensor is where the leak suggests Suunto has made its most consequential hardware rethink. Wrist-based heart rate has long been the brand’s weakest link, especially during high-intensity running, cold-weather use, and technical trail sessions where motion artefacts spike.

According to the leaked materials, both the Race 2 and Vertical 2 debut an all-new optical heart rate module rather than a minor revision of the existing package. That distinction matters, because it points to a structural change in how Suunto is capturing and processing cardiovascular data, not just tweaking algorithms on familiar hardware.

A New Sensor Stack, Not Just More LEDs

The leak references a redesigned sensor array with a higher-density photodiode layout and a revised LED configuration. While Suunto does not appear to be chasing raw LED count numbers in marketing terms, the emphasis is on improved signal capture across a wider range of skin tones, wrist shapes, and strap tensions.

In practical terms, this suggests a move away from the older “brute force” approach where brighter LEDs compensated for noisy data. Instead, Suunto seems to be prioritizing cleaner initial signal acquisition, which reduces the need for aggressive post-processing that can introduce lag or smoothing errors during intervals.

The physical sensor window is also subtly reworked, with changes to lens geometry and skin contact area noted in the leak imagery. That has implications for comfort and stability, especially during long runs or ultra events where wrist swelling and micro-movement can degrade optical accuracy over time.

Improved Motion Artefact Rejection During Intensity

Where this new sensor could be most impactful is during high-cadence running and rapid pace changes. Historically, Suunto watches have trailed Garmin’s Elevate Gen 4 and COROS’ latest optical systems when it comes to tracking intervals, hill repeats, and surges without drifting or locking late.

The leaked documentation specifically mentions improved motion artefact rejection tied to faster sampling and more localized signal analysis. That aligns with the previously discussed chipset upgrade, as better compute throughput allows the watch to discard bad data faster rather than averaging it into the heart rate trace.

For athletes, this translates to fewer mid-workout spikes, less delayed heart rate response at the start of hard efforts, and more trustworthy data for structured training plans. It also reduces the psychological friction that pushes serious runners toward chest straps by default.

Cold Weather, Low Perfusion, and Trail Use

Another area where Suunto has struggled is cold-weather performance, particularly for Nordic users who train outdoors year-round. Reduced blood flow at the wrist has traditionally exposed weaknesses in older optical sensors, leading to dropouts or flatlined readings early in winter sessions.

The new sensor is described as having improved low-perfusion detection, likely combining hardware sensitivity with smarter duty cycling. Instead of simply increasing LED power when signal quality drops, the system appears to adjust sampling behavior dynamically to preserve accuracy without destroying battery life.

Trail runners and mountaineers also stand to benefit, as uneven terrain amplifies wrist movement and vibration. If the leak claims hold up in testing, this would represent a meaningful quality-of-life upgrade for Suunto’s core audience rather than a lab-only improvement.

Battery Life Trade-offs and Efficiency Gains

One of the more understated but important aspects of the new heart rate sensor is how it interacts with battery life. More capable sensors often come with higher power demands, yet the leaked endurance figures for both watches show stability or slight improvement.

That points to efficiency gains rather than raw power increases. By capturing cleaner data earlier in the pipeline, the system can reduce LED brightness, shorten sampling windows, or avoid unnecessary retries, all of which save energy over multi-hour activities.

This is especially relevant for the Vertical 2, where ultra-long GPS modes and solar-assisted charging already push the platform to its limits. A more efficient heart rate sensor helps preserve Suunto’s expedition credentials without forcing users to compromise on physiological tracking.

How It Compares to Garmin and COROS Right Now

On paper, this new optical heart rate sensor positions Suunto much closer to parity with Garmin’s latest Elevate implementations and COROS’ recent hardware revisions. It does not appear to leapfrog them outright, but it closes gaps that were increasingly difficult to ignore at this price tier.

Garmin still holds an edge in algorithm maturity and ecosystem integration, particularly for heart rate-based training load and recovery metrics. COROS remains strong in consistency during steady-state endurance efforts, especially at lighter watch weights.

What Suunto gains here is credibility. If real-world testing confirms reliable performance across intervals, trails, and cold conditions, the Race 2 and Vertical 2 would finally allow athletes to trust wrist heart rate data as a default rather than a fallback.

What’s Truly New Versus Iterative

It’s important to separate genuine hardware change from refinement. This sensor is not just a tuned version of what came before; the physical layout, signal capture strategy, and processing pipeline all appear to be new.

At the same time, it is not a radical reinvention of optical heart rate technology as a whole. There is no indication of novel wavelengths, medical-grade aspirations, or category-defining breakthroughs.

What it represents instead is Suunto doing the fundamentals properly at last. In a market where small accuracy gains have outsized impact on training decisions, that may prove to be one of the most important upgrades in this entire leak.

Under the Hood: New Chipset, GNSS Platform, and Processing Power Explained

If the new heart rate sensor fixes one of Suunto’s most visible weaknesses, the leaked internal hardware changes address something more foundational: how quickly, efficiently, and intelligently the Race 2 and Vertical 2 can process everything happening at once. Sensor data, maps, GNSS positioning, UI animations, and battery management all live or die by the silicon underneath.

The full leak strongly suggests that Suunto is not simply reusing the same processing platform from the original Race and Vertical. Instead, both watches appear to be built around a newer, more capable system-on-chip paired with an updated GNSS module, marking a rare generational shift for the brand.

A New Wearable SoC, Not Just a Clock Speed Bump

While Suunto has not named the chipset in the leaked materials, multiple indicators point to a move away from the older ultra-low-power MCU used in recent models. The UI fluidity shown in leaked videos, faster map redraws, and near-instant menu transitions all imply a more modern wearable-focused SoC rather than a lightly refreshed microcontroller.

This matters because Suunto’s previous hardware often felt computationally constrained. Tasks like panning maps, recalculating routes, or switching data screens during activities could introduce noticeable lag, especially when dual-band GNSS was active.

A newer SoC likely brings higher memory bandwidth, better sensor co-processing, and more efficient power domains. In practical terms, that translates to smoother navigation, quicker activity start times, and less compromise between performance and battery life during long sessions.

GNSS Platform Upgrade: Multi-Band Without the Penalty

The leak also points to an updated GNSS chipset, very likely a newer-generation multi-band solution from Sony or Airoha rather than the older Sony CXD5603 family. This is a crucial distinction, because early multi-band implementations across the industry often came with heavy power costs.

What appears different here is how aggressively Suunto is leaning into efficiency. The Race 2 and Vertical 2 are expected to support dual-frequency GNSS across all major constellations, but with smarter signal selection and adaptive sampling rather than brute-force tracking.

For runners and trail athletes, this should mean more consistent track quality in forests, canyons, and urban corridors without the dramatic battery hit seen in first-wave dual-band watches. For ultrarunners and expedition users, it preserves Suunto’s long-standing advantage in endurance modes while finally modernizing positional accuracy.

Processing Power and Maps: Where the Difference Is Felt Most

Offline maps have become a defining feature of Suunto’s recent watches, but they also exposed the limits of older hardware. Zooming, panning, and rerouting could feel sluggish compared to Garmin’s Epix or Apple’s Watch Ultra, even when the data itself was excellent.

The leaked Race 2 footage shows materially faster map interactions, suggesting not just better software optimization but real gains in CPU and possibly GPU capability. This is one of the clearest signs that Suunto has invested in a more capable processing platform rather than simply tuning firmware.

For navigation-heavy users, this affects more than aesthetics. Faster redraws reduce cognitive load mid-run or mid-climb, making the watch easier to trust when quick decisions matter.

Battery Efficiency: The Silent Beneficiary

More powerful chips often raise concerns about battery life, but modern wearable silicon flips that equation. Newer SoCs typically complete tasks faster and return to low-power states sooner, reducing overall energy consumption despite higher peak performance.

Combined with the new heart rate sensor’s efficiency gains, the chipset upgrade likely plays a major role in maintaining Suunto’s class-leading endurance claims. Especially on the Vertical 2, where solar charging supplements but does not replace battery capacity, every watt saved at the silicon level compounds over multi-day use.

This is where Suunto’s traditionally conservative hardware philosophy starts to look strategic rather than outdated. Instead of chasing smartphone-like performance, the focus remains on sustained reliability under continuous load.

How This Positions Suunto Against Garmin and COROS

Garmin still sets the benchmark for UI responsiveness and computational headroom, particularly on AMOLED models like the Epix Pro. Apple dominates raw processing power but sacrifices endurance in the process. COROS sits somewhere in between, favoring efficiency over polish.

With the Race 2 and Vertical 2, Suunto appears to be closing the gap without abandoning its core identity. The leaked hardware suggests enough processing muscle to eliminate obvious friction points while preserving the battery life that endurance athletes demand.

This does not suddenly make Suunto the performance king in every category. What it does is remove the sense that Suunto is always one hardware generation behind, which has quietly shaped buyer perception for years.

What’s Confirmed, What’s Inferred

Confirmed by the leak are faster UI interactions, updated GNSS behavior, and clear signs of a new internal platform shared across both models. Also evident is a tighter integration between sensors, GNSS, and processing, rather than bolt-on upgrades.

What remains inferred is the exact silicon vendor, memory configuration, and whether Suunto has added dedicated co-processors for sensor fusion or GNSS filtering. Those details will matter for edge cases like interval-heavy training and complex navigation scenarios.

Still, taken as a whole, the chipset and GNSS changes appear to be as meaningful as the new heart rate sensor. Together, they suggest that the Race 2 and Vertical 2 are not just refinements, but the beginning of a more competitive hardware era for Suunto.

Real-World Impact: Heart Rate Accuracy, GPS Precision, and Responsiveness

What ultimately determines whether these leaked upgrades matter is not the spec sheet, but how they translate under sweat, motion, cold, and fatigue. The combination of a new optical heart rate sensor, updated GNSS behavior, and a faster internal platform suggests changes that endurance athletes will feel immediately, not just measure after the fact.

This is where the Race 2 and Vertical 2 appear to move beyond iterative refreshes and into tangible day-to-day performance gains.

Optical Heart Rate: Fewer Spikes, Faster Lock, Better Effort Tracking

The leaked heart rate sensor appears to be a new multi-LED, multi-wavelength optical array, likely expanding beyond Suunto’s previous red/green-heavy configuration. While Suunto has not confirmed the exact diode mix, the layout and increased sensor surface area point toward improved penetration depth and better handling of rapid intensity changes.

In practical terms, this should reduce the classic Suunto weaknesses: early-activity lag, interval overshoot, and cadence lock during hard running. Faster signal acquisition at the start of an activity matters for interval sessions and structured workouts, where the first few minutes often set the tone for training load calculations.

For trail runners and mountain athletes, improved optical consistency during wrist angle changes is arguably more important than lab-grade accuracy. If the new sensor maintains cleaner heart rate curves during climbs, pole use, and technical descents, it would close much of the real-world gap to Garmin’s Elevate Gen 5 and Apple’s current optical stack, without requiring a chest strap for every session.

GNSS Precision: Cleaner Tracks Without Battery Penalty

The leak indicates refined multi-band GNSS behavior rather than a wholesale change in satellite hardware. This suggests improved signal filtering, faster convergence, and smarter sensor fusion between accelerometer, compass, and satellite data, all driven by the updated chipset.

For athletes, this translates into cleaner cornering on switchbacks, reduced “track wobble” in forests and urban corridors, and more stable pace reporting. The Vertical 2, in particular, stands to benefit in alpine terrain, where vertical oscillation and poor sky view historically exposed GNSS weaknesses.

Crucially, these gains appear to come without the aggressive battery drain seen on some competitors when full multi-band mode is enabled. If Suunto has managed to refine GNSS efficiency rather than brute-forcing accuracy, it reinforces the brand’s endurance-first philosophy while still delivering modern-level precision.

Responsiveness: Subtle, But Finally Competitive

UI responsiveness has long been the quiet frustration for Suunto loyalists, not because the watches were unusable, but because they felt one step behind the athlete’s intent. The leaked platform shows clear improvements in touch response, screen redraws, and menu transitions, especially on AMOLED-equipped Race 2 units.

This matters most during high-cognitive-load moments: starting intervals, scrolling data pages mid-run, rerouting during navigation, or marking laps with cold or gloved hands. Even modest reductions in input latency can change how confident a watch feels when you are already physically taxed.

Importantly, this does not suggest Suunto is chasing Garmin’s most fluid AMOLED experiences or Apple’s brute-force processing. Instead, it looks like a deliberate move to eliminate friction without sacrificing stability or battery life, keeping the focus on predictable performance rather than visual flash.

Sensor Fusion and Consistency Over Time

One of the more underappreciated implications of the new chipset is how it enables tighter coordination between heart rate, GNSS, and motion sensors. Better sensor fusion can smooth out data anomalies before they reach the user, resulting in more believable pace, effort, and recovery metrics.

Over long training blocks, this consistency matters more than peak accuracy. Athletes rely on trends, not isolated data points, and fewer outliers mean better trust in training load, HRV-derived insights, and fatigue indicators.

If the Race 2 and Vertical 2 deliver cleaner data with less manual intervention, fewer reboots, and fewer moments of doubt mid-activity, that alone represents a meaningful upgrade for serious users who train daily.

Battery Life as the Silent Enabler

None of these improvements would hold much value if they came at the cost of endurance, and the leak strongly suggests that battery life remains intact, if not slightly improved. More efficient processing and smarter GNSS handling mean the watches can afford better accuracy without reverting to conservative modes.

For ultra runners, expedition athletes, and multi-day racers, this balance is where Suunto traditionally excels. The ability to trust heart rate and GPS data deep into a long effort, without constantly managing power modes, is still a differentiator in this segment.

Seen through that lens, the hardware changes in the Race 2 and Vertical 2 are not about chasing headline specs. They are about reinforcing Suunto’s core promise, while finally removing enough technical friction to compete head-to-head with Garmin and COROS on real-world performance, not just endurance claims.

Battery Life and Efficiency: Does the New Silicon Deliver Meaningful Gains?

If the previous sections established why Suunto’s new sensor and chipset matter for data quality, battery life is where those choices are either validated or exposed. According to the leak, Suunto has prioritized efficiency gains at the silicon level rather than chasing larger batteries or more aggressive power-saving modes.

This approach aligns closely with Suunto’s recent philosophy. Instead of advertising extreme headline numbers that require compromises, the Race 2 and Vertical 2 appear designed to deliver stable, repeatable endurance across real training weeks, not just ideal lab scenarios.

What the Leak Suggests About the New Processor

The leaked internal documentation points to a new-generation wearable SoC with materially lower idle and sensor-processing power draw. While Suunto has not publicly named the silicon yet, the shift appears comparable to the jump Garmin made when it moved to newer low-power ARM-based platforms with better co-processor handling.

In practical terms, this means background tasks like wrist heart rate sampling, motion detection, and UI responsiveness can run more frequently without waking the main cores. That alone can shave meaningful percentages off daily drain, especially for athletes who wear their watches 24/7.

For Race 2 users in particular, this matters because AMOLED displays amplify inefficiencies elsewhere. If the chipset can do more work while the display remains off, Suunto can preserve endurance without dimming the screen aggressively or relying on short timeouts that hurt usability.

GNSS Efficiency: Accuracy Without Paying the Battery Tax

The leak also hints at improved GNSS power management, likely tied to tighter integration between the processor and the GNSS chip rather than a dramatic change in satellite hardware. That suggests smarter duty cycling, faster lock acquisition, and fewer fallback states during challenging conditions.

For runners and trail athletes, this can translate into lower consumption during long sessions without downgrading to Ultra or Endurance GPS modes. The Vertical 2, especially when paired with solar assistance, looks positioned to maintain full multi-band accuracy deeper into multi-day efforts than the current model.

This is where Suunto’s approach diverges from COROS. Rather than pushing extreme battery claims through aggressive smoothing and sampling reduction, the leaked specs suggest Suunto is trying to make its highest accuracy modes more affordable from a power standpoint.

Race 2 vs Vertical 2: Different Displays, Same Efficiency Story

Despite sharing much of the internal architecture, the Race 2 and Vertical 2 will inevitably express these efficiency gains differently. The Race 2’s AMOLED panel remains the largest single drain, but the new chipset appears to offset that with reduced background consumption and more intelligent refresh behavior.

Early leak estimates suggest modest but real gains in smartwatch mode and equivalent or slightly better endurance in full-accuracy GPS workouts compared to the current Race. That is notable because it implies Suunto is not trading accuracy or UI smoothness to get there.

The Vertical 2 benefits even more directly. With a transflective display and solar input, any reduction in baseline power draw compounds over time, potentially extending expedition-style use cases where charging is infrequent or impractical.

Always-On Sensors and the Cost of Consistency

One underreported advantage of the new silicon is how it changes the economics of always-on sensing. Continuous heart rate, SpO2 spot checks, HRV tracking, and overnight recovery metrics all consume small but persistent amounts of power.

By lowering the cost of these background measurements, Suunto can afford to keep them running without forcing users to choose between data completeness and battery life. That reinforces the theme from earlier sections: consistency over peak performance.

For athletes training daily, fewer compromises mean fewer decisions. You can trust the watch to collect the data you need without constantly toggling features off to survive the week.

How This Positions Suunto Against Garmin and COROS

Garmin still holds an advantage in absolute efficiency thanks to its custom silicon and years of iteration. However, the leaked Race 2 and Vertical 2 specs suggest Suunto is closing the gap in the areas that matter most during training, not just on spec sheets.

Compared to COROS, Suunto appears to be prioritizing accuracy stability and sensor quality first, then optimizing battery life around those goals. That strategy may result in slightly lower headline endurance claims, but higher trust in the data collected during long, complex activities.

If these efficiency gains hold up in real-world testing, the Race 2 and Vertical 2 would represent a meaningful recalibration for Suunto. Not a battery-life revolution, but a clear signal that the company’s hardware foundation is finally modern enough to support its ambitions without asking users to compromise.

Race 2 vs Vertical 2: How Suunto Is Differentiating Its High-End Lineup

With the silicon and sensor story now largely shared between the two leaked models, the more interesting question becomes how Suunto is using the Race 2 and Vertical 2 to serve distinctly different athletes. The leaks suggest this is less about feature gating and more about physical design, display philosophy, and use-case prioritization.

Rather than a simple “good, better, best” ladder, Suunto appears to be splitting its flagship line along indoor–outdoor and performance–expedition lines, while keeping the underlying hardware platform consistent.

Shared Core: Same Engine, Different Missions

According to the leak, both Race 2 and Vertical 2 run on the same new chipset and share the updated optical heart rate sensor. That is significant, because it means Suunto is no longer reserving its best sensing hardware for a single halo device.

From a data perspective, a Race 2 worn during interval training and a Vertical 2 worn during a multi-day alpine traverse should be collecting fundamentally comparable heart rate, HRV, and activity metrics. That consistency matters for athletes who rotate watches depending on season or discipline.

This also simplifies Suunto’s software burden. When both watches ingest similar-quality sensor data at similar sampling rates, algorithm tuning and feature rollouts become less fragmented than in previous generations.

Display Strategy: AMOLED Performance vs Transflective Endurance

The clearest differentiation remains the display. Race 2 continues with a high-resolution AMOLED panel, tuned for contrast, color, and legibility during fast-paced training and daily wear.

That choice aligns with the Race branding. AMOLED excels during intervals, track sessions, gym workouts, and urban running where quick glances, smooth animations, and rich data screens improve usability.

Vertical 2, by contrast, sticks with a transflective display, now paired again with solar charging. This is not about aesthetics but about survivability. Transflective panels remain readable in harsh sun, draw almost no power when static, and pair naturally with the new low-power chipset for extended outdoor use.

Battery Life: Similar Gains, Different Payoffs

Both watches benefit from the reduced baseline power draw discussed earlier, but the way that translates into user value diverges. On Race 2, the gain shows up as flexibility: always-on heart rate, higher GPS accuracy modes, and smoother UI without sacrificing a full week of mixed use.

For Vertical 2, the same efficiency compounds over much longer timelines. When combined with solar input and a larger physical battery, the new chipset potentially pushes Vertical 2 deeper into expedition territory, where charging opportunities are measured in days, not hours.

This reinforces the idea that Suunto is optimizing Race 2 for training density and Vertical 2 for duration density. One is about doing more per hour, the other about surviving more hours overall.

Form Factor, Materials, and Wearability

Leaks point to Race 2 retaining a more compact and urban-friendly case profile, closer to the original Race but refined in thickness and weight distribution. This matters for comfort during daily wear, sleep tracking, and fast workouts where wrist movement is frequent.

Vertical 2 remains unapologetically larger. The extra surface area supports the solar ring, larger battery, and enhanced thermal management during prolonged GPS usage, but it also makes the watch feel more like a piece of outdoor equipment than a lifestyle device.

Materials further reinforce this split. Race 2 leans into clean finishing and lighter construction, while Vertical 2 prioritizes durability, bezel protection, and resistance to environmental abuse over visual subtlety.

Software Experience: Same Features, Different Defaults

While the software stack appears largely identical on paper, default configurations are likely where Suunto draws the line. Race 2 is expected to ship with AMOLED-optimized watch faces, denser data screens, and more aggressive refresh behavior.

Vertical 2 will almost certainly bias toward conservative refresh rates, solar-aware battery modes, and navigation-first layouts. The same features exist, but the watch nudges the user toward different behaviors out of the box.

This approach avoids alienating power users while still guiding less technical athletes toward setups that match the hardware’s strengths.

Why This Matters for Suunto’s Competitive Position

Garmin has long segmented its lineup this way, but often with different processors or sensor generations across models. COROS, meanwhile, emphasizes simplicity and battery life, sometimes at the cost of display richness or daily wear appeal.

By giving both Race 2 and Vertical 2 the same modern heart rate sensor and chipset, Suunto is signaling that accuracy and responsiveness are now baseline expectations, not premium differentiators.

The differentiation shifts to philosophy rather than capability. That is a more mature position for a performance brand, and if real-world testing confirms the leaks, it suggests Suunto is finally competing on equal hardware footing while letting athletes choose the tool that best matches how and where they train.

Design, Display, and Durability: What the Leak Confirms (and What It Doesn’t)

If the sensor and chipset leaks establish that Race 2 and Vertical 2 are finally equals under the hood, the industrial design details are where Suunto still draws a very deliberate line. The leaked renders, certification photos, and spec tables don’t suggest a radical redesign for either model, but they do confirm refinement rather than stasis.

This is evolutionary hardware done with intent, and the differences matter more in daily wear and long sessions than they do on a spec sheet.

Case Design and Physical Dimensions

Race 2 appears to retain the slim, modern silhouette introduced with the original Race, including the rounded case profile and relatively compact lug-to-lug. Leaked measurements point to marginal thickness reduction rather than a size jump, suggesting Suunto focused on internal layout efficiency rather than chasing bigger batteries or louder aesthetics.

That matters for runners and triathletes who actually wear the watch 24/7. A lighter case and tighter profile reduce wrist fatigue over long runs and make sleep tracking less intrusive, something the original Race already did better than many Garmin Fenix-class competitors.

Vertical 2, by contrast, doubles down on its tool-watch identity. Case dimensions remain large, and the geometry is still unapologetically blocky, optimized for protection and internal volume rather than subtlety. This is consistent with the Vertical’s role as Suunto’s expedition-first platform, not a hybrid lifestyle watch.

Materials, Finishing, and Real-World Durability

Leaks confirm familiar material choices rather than surprises. Race 2 continues with stainless steel and titanium variants, paired with Gorilla Glass or sapphire depending on configuration. The finishing appears cleaner and more uniform in the leaked imagery, suggesting Suunto has tightened tolerances rather than changed materials.

This keeps Race 2 competitive with Garmin’s Forerunner 965 and Epix line, where perceived quality matters almost as much as performance metrics. It also reinforces that Race 2 is meant to be worn beyond training sessions, not just during them.

Vertical 2 remains the durability-first option. Titanium bezel, reinforced case edges, and sapphire glass are again front and center, and there’s no indication Suunto is softening this approach. Water resistance ratings appear unchanged, which implies the internal redesign for the new chipset and heart rate sensor didn’t compromise sealing or structural integrity.

Display Technology: AMOLED Versus MIP, Confirmed

The display split is one of the few areas where the leak leaves no ambiguity. Race 2 sticks with AMOLED, likely using a newer panel with improved efficiency rather than higher peak brightness. Resolution and size appear broadly similar to the original Race, reinforcing that Suunto prioritizes clarity and contrast over raw pixel density.

What’s not confirmed is a major jump in outdoor brightness or adaptive refresh sophistication. If improvements exist, they are likely incremental and tied to the new chipset’s display controller rather than a dramatic panel upgrade.

Vertical 2 continues with a transflective MIP display, surrounded by the solar charging ring. The leak does not suggest a switch to higher resolution or color depth, which aligns with Suunto’s philosophy of legibility over visual flair. For navigation-heavy use, especially in harsh sunlight or winter conditions, this remains a practical choice.

Solar Integration and Structural Trade-Offs

Solar capability on Vertical 2 appears unchanged in concept but refined in execution. The bezel-integrated solar ring is still present, and the larger case accommodates it without crowding the display. There’s no indication of a breakthrough in solar efficiency, but even modest gains would stack with the improved chipset efficiency discussed earlier in the leak.

Race 2 does not gain solar, and that omission feels intentional rather than cost-driven. Adding solar would have required compromises in display size or case thickness, undercutting the watch’s primary appeal as a lighter, more wearable performance device.

Buttons, Touch, and Interaction Durability

Both watches retain the familiar three-button layout with touchscreen support. Leaked images suggest no redesign of button guards or crown-style inputs, which indicates Suunto is confident in the existing ergonomics.

That’s notable because physical controls are often overlooked in leak discussions, yet they define usability in rain, snow, and gloves. Vertical 2’s buttons appear more recessed and protected, reinforcing its expedition bias, while Race 2’s remain easier to actuate during high-intensity workouts.

What the Leak Still Doesn’t Answer

Despite the volume of material, some key durability questions remain unanswered. We don’t yet know if Suunto has improved vibration motor strength, speaker sealing, or long-term AMOLED burn-in mitigation on Race 2.

Likewise, there’s no confirmation of changes to strap attachment tolerances or third-party compatibility, which directly affects comfort and customization for endurance athletes. These details often separate a good watch from a great one over months of use.

What the leak does confirm is that Suunto hasn’t chased novelty for its own sake. Design, display, and durability choices remain tightly aligned with how each watch is meant to be used, and the internal hardware upgrades appear to have been integrated without compromising those identities.

How Race 2 and Vertical 2 Stack Up Against Garmin, COROS, and Apple Watch Ultra

With the hardware picture now clearer, the Race 2 and Vertical 2 can be positioned more precisely against their real rivals. This isn’t about feature checklists so much as how Suunto’s new sensor stack and silicon choices affect accuracy, battery life, and day-to-day usability compared to Garmin, COROS, and Apple.

Heart Rate Sensor: Catching Up, Not Leapfrogging

The leaked heart rate module appears to be Suunto’s most meaningful optical upgrade in years, but it should be framed as convergence rather than domination. The multi-LED layout and denser photodiode arrangement bring Suunto closer to Garmin’s Elevate Gen 5 and COROS’ latest sensor array, particularly for interval-heavy running and tempo work.

What’s still unclear is whether Suunto has meaningfully improved motion artifact rejection in cold conditions and downhill trail running, areas where Garmin’s latest firmware tuning has been quietly strong. Apple Watch Ultra remains the benchmark for wrist-based heart rate during mixed-intensity workouts, especially when paired with Apple’s aggressive data smoothing and high sampling rates, though it achieves this at a steep battery cost.

For athletes who rely on chest straps, the gap matters less. For those who don’t, Race 2 and Vertical 2 finally look competitive rather than compromised.

GNSS and Chipset: Efficiency Over Raw Firepower

The leaked chipset shift is arguably more important than the new heart rate sensor. Suunto appears to have moved to a newer-generation low-power wearable SoC paired with a modern dual-band GNSS solution, prioritizing sustained accuracy and battery stability rather than peak processing bursts.

Against Garmin, this places Suunto in an interesting middle ground. Garmin’s latest Fenix and Forerunner models still lead in multi-band consistency under dense tree cover and urban canyoning, but they also lean heavily on proprietary power management tricks to maintain battery life.

COROS continues to be the battery endurance king, particularly in expedition modes, yet its UI responsiveness and map redraw speeds still lag behind what Suunto is now hinting at. Apple Watch Ultra, powered by Apple’s S-series silicon, is in a different category altogether, delivering unmatched UI fluidity and sensor fusion while remaining fundamentally constrained by daily or near-daily charging.

Battery Life vs Real-World Usability

Vertical 2’s positioning remains clear: long-haul endurance with minimal user intervention. Even without a solar breakthrough, incremental efficiency gains from the new chipset could compound meaningfully over multi-day outings, especially when paired with Suunto’s already conservative background power usage.

Race 2 is the more interesting comparison piece. It directly challenges Garmin’s AMOLED-equipped Forerunners by promising similar visual clarity with fewer battery penalties, though Garmin still holds an advantage in adaptive display dimming and glanceable data density.

Apple Watch Ultra continues to trail badly here for endurance athletes, despite improvements in Low Power Mode. For ultras, fastpacking, and stage racing, charging logistics still make it a secondary device rather than a primary one.

Software, Ecosystem, and Training Depth

Hardware parity only matters if the software can exploit it. Garmin remains untouchable in native training analytics, recovery metrics, and third-party platform integrations, especially for triathletes and data-driven runners.

Suunto’s advantage lies in clarity and restraint. The new hardware should allow faster map interactions, smoother breadcrumb navigation, and more responsive workout screens, areas where previous Suunto models occasionally felt underpowered rather than underdesigned.

COROS sits between the two, offering strong fundamentals with fewer bells and whistles, while Apple’s ecosystem excels at health aggregation and lifestyle integration but still feels awkward for structured endurance training without external apps.

Build, Comfort, and Wearability Trade-Offs

Physically, neither Race 2 nor Vertical 2 appears to chase extremes. Case dimensions, materials, and strap systems remain familiar, which will appeal to long-time Suunto users who value predictable comfort over radical redesigns.

Garmin offers more size and material variants, including lighter polymer builds and premium titanium options. Apple Watch Ultra feels dense and luxurious but polarizing on smaller wrists, while COROS continues to prioritize low weight over tactile refinement.

Suunto’s strength here is balance. Race 2 looks optimized for daily wear without losing its performance identity, while Vertical 2 retains the purposeful bulk expected of an expedition-focused tool.

What This Means for Suunto’s Competitive Standing

Taken together, the leaks suggest Suunto is no longer playing defense. The Race 2 and Vertical 2 don’t redefine the category, but they remove several long-standing excuses for choosing Garmin or COROS by default.

The new heart rate sensor and chipset don’t promise miracles, yet they address the exact pain points that previously limited Suunto’s appeal among serious athletes. If real-world testing confirms the expected gains in accuracy, efficiency, and responsiveness, Suunto re-enters the top-tier conversation not as a nostalgic alternative, but as a credible, modern competitor.

Big Picture Verdict: Is This a True Step Forward for Suunto or a Catch-Up Move?

The Race 2 and Vertical 2 leaks land at an important inflection point for Suunto. After several years of strong design fundamentals held back by aging silicon and inconsistent optical heart rate performance, these watches appear to directly target the weakest links in Suunto’s stack rather than chasing headline features.

This is not a moonshot release, but it is far from cosmetic. The question is whether fixing fundamentals is enough in a market where Garmin and COROS have been refining theirs for multiple generations.

A Catch-Up on Paper, a Leap in Practice

Strictly speaking, neither the new heart rate sensor nor the updated chipset sounds revolutionary in isolation. Multi-LED optical sensors, improved photodiode layouts, and modern low-power GNSS-capable SoCs are now table stakes at the high end of the sports watch market.

Where this becomes more than catch-up is in context. Suunto’s previous bottlenecks meant that even well-designed software features felt constrained in motion, especially during interval-heavy workouts, fast map panning, or long multi-band GNSS activities where battery drain spiked faster than expected.

If the leaked hardware performs as anticipated, Suunto finally removes those constraints. That enables the existing Suunto experience to operate at the level it always promised, rather than forcing users to tolerate minor but persistent friction.

Why the New Sensor and Chip Actually Matter Day to Day

For athletes, the optical heart rate upgrade is about trust more than novelty. Better skin contact tolerance, improved motion artifact rejection, and stronger signal consistency mean fewer spikes during tempo runs, steadier HRV trends overnight, and less reliance on chest straps for routine training.

The chipset upgrade matters just as much, if not more. Faster UI response, smoother map redraws, and more efficient GNSS processing translate directly into confidence during long trail runs or navigation-heavy adventures, where lag or dropped accuracy compounds fatigue rather than merely inconveniencing the user.

Battery life gains, even modest ones, are especially meaningful for Suunto’s audience. A Vertical 2 that maintains solar-assisted endurance while handling multi-band GNSS and richer maps more efficiently reinforces its positioning as a true expedition watch, not just a long-lasting one.

Competitive Positioning: Narrowing the Gap, Not Redrawing the Map

Against Garmin, Suunto still trails in ecosystem depth and third-party platform integrations, especially for triathletes managing complex training calendars. Garmin’s advantage lies in breadth and polish built over many years, not just hardware.

Against COROS, the gap becomes more nuanced. COROS often wins on battery efficiency and value, but Suunto counters with superior cartography, cleaner interface design, and a more refined physical product, particularly in materials, finishing, and strap comfort for all-day wear.

Apple Watch Ultra remains a different proposition entirely. Its health sensors and smartwatch fluidity are unmatched, but its training workflows, battery constraints for ultra-distance events, and reliance on apps keep it from directly replacing a Race 2 or Vertical 2 for serious endurance athletes.

So, Is This Enough?

The honest verdict is that this is both a catch-up move and a genuine step forward. Suunto is catching up in silicon and sensor capability, but that catch-up unlocks a forward leap in real-world usability, reliability, and competitiveness.

For existing Suunto users, the leaks suggest the upgrade many have been waiting for: familiar ergonomics and design, now backed by hardware that no longer feels one generation behind. For athletes considering a switch from Garmin or COROS, the Race 2 and Vertical 2 finally remove several practical reasons not to choose Suunto.

Assuming the leaked details hold up in shipping units, this is Suunto reasserting relevance at the top end of the sports watch market. Not by reinventing the category, but by executing the fundamentals well enough that the watch disappears on the wrist and simply does its job, which, for performance-focused athletes, is the highest compliment of all.
