The timing was conspicuously late: Google had already detailed Wear OS 5 in May, and Samsung’s first Wear OS 5 watches began shipping in July. The announcement confirmed Wear OS 4 for two models—not Wear OS 5, and not every TicWatch.
Which TicWatch models received Wear OS 4?
Mobvoi’s announcement covered only the TicWatch Pro 5 and TicWatch Pro 5 Enduro. Both were to be upgraded from Wear OS 3.5. Mobvoi said distribution would begin in early September 2024 and continue in phases, with availability varying by region and device. Eligible owners would receive an on-watch notification.
That wording does not establish eligibility for the TicWatch Pro 3, Pro 3 Ultra, E3, Atlas, or any other model. Those watches require separate, model-specific confirmation. The announcement is documented by Mobvoi’s September 3, 2024 notice.
Why the update was considered late
| Date | Event | What it means |
|---|---|---|
| May 2024 | Google detailed Wear OS 5 | The next major platform version was public before Mobvoi announced its Wear OS 4 plan. |
| July 2024 | Samsung announced Galaxy Watch7 and Galaxy Watch Ultra | They were identified as the first Wear OS 5 smartwatches. |
| September 3, 2024 | Mobvoi announced its Wear OS 4 rollout | Pro 5 owners were moving from Wear OS 3.5 to Wear OS 4 while Wear OS 5 was already entering the market. |
Google’s May announcement described Wear OS 5 improvements including power-efficiency work and additional workout metrics. Samsung’s first hardware announcement followed in July. Against that timeline, Mobvoi’s September announcement was a delayed catch-up, although calling the watches “two generations behind” would be misleading: Mobvoi was moving from 3.5 to 4, while version 5 was the newer release beginning to ship elsewhere.

What Wear OS 4 adds on the Pro 5 and Pro 5 Enduro
System and setup changes
- Backup and restore: Mobvoi says data, settings, and watch faces can be backed up and restored.
- Phone transfer: The watch can be transferred to a new smartphone without requiring a factory reset. The exact screens can differ by firmware, phone, region, and Mobvoi’s companion software, so back up important information before pairing changes.
- System optimization: The update includes general system changes and a security patch dated September 2024.
Mobvoi fitness and workout changes
- Improved automatic cycling detection.
- Workout information shown on the ultra-low-power display during the pre-identification period.
- More frequent data detection while a workout is being identified.
- Additional GPS data.
- Twenty-five new professional workout modes.
- Expanded outdoor statistics such as GPS, distance, and speed.
- A reorganized workout list that can be customized.
These fitness and workout items are described in Mobvoi’s announcement and belong largely to Mobvoi’s TicMotion/TicExercise software experience. They should not be treated as features supplied by Google’s base Wear OS alone.
How to check for the update
- Wake the watch and press the Power button to open the app list.
- Open Settings.
- Choose System → About → System updates.
- If an update is offered, download it and leave the watch undisturbed while it installs.
For watch-app updates, open the watch’s Play Store, swipe down from the top, tap My Apps, then select individual updates or Update all. Google recommends Wi-Fi. Keep the watch charged, keep it near the phone, and update Mobvoi’s companion apps if prompted.
Rank #2
- Rugged Titanium Case: Durable titanium design built for outdoor activities and demanding environments.
Menu names can vary by manufacturer and software version. Check the operating-system version on the watch itself; the version displayed in a phone companion app is not necessarily the watch’s OS version. Google’s instructions are at Wear OS Help.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
If Wear OS 4 is not showing
- Confirm the watch is connected to Wi-Fi and has sufficient charge.
- Recheck Settings → System → About → System updates.
- Install pending Play Store and companion-app updates.
- Restart both the watch and phone.
- Temporarily turn off Bluetooth and retry, following Google’s troubleshooting guidance.
- Allow for the phased regional rollout; a missing prompt does not by itself prove the model is unsupported.
- Contact Mobvoi if the watch remains on an unexpected or unsupported build after rollout availability should have reached the region.
Does this guarantee Wear OS 5?
No. Mobvoi announced Wear OS 4 only. It provided no Wear OS 5 schedule or promise for the Pro 5, Pro 5 Enduro, or other TicWatch models in that announcement. Receiving one major update is not evidence that a watch will receive the next one; a later release would require a separate official statement.
Wear OS 5’s platform claims also should not be applied retroactively to these watches. Google said Wear OS 5 could use up to 20% less power during an outdoor marathon than Wear OS 4 and added metrics such as ground-contact time, stride length, and vertical oscillation. Those are Google’s platform-level claims, not independently measured results for a TicWatch running Mobvoi’s Wear OS 4 build.

Google has since announced Wear OS 7 and said it was rolling out to eligible Pixel Watch devices in 2026. That shows how far the platform has advanced, but it does not establish eligibility for older Mobvoi watches. See Google’s 2026 Wear OS announcement.

Why install
- Backup and restore reduce the risk and effort of changing phones.
- Phone transfer avoids the factory-reset requirement described for the prior setup.
- New workout modes, cycling detection, GPS information, and outdoor statistics expand the fitness feature set.
- The build includes the September 2024 security patch named by Mobvoi.
When waiting briefly is sensible
A major OS update can affect battery behavior, pairing, sensors, watch faces, or third-party apps. If the watch is essential for work, travel, or training, back up data, record critical settings, update dependent apps, and wait for early owner reports before installing immediately. Waiting does not create a Wear OS 5 entitlement; it simply gives a phased rollout time to expose and resolve problems.
What the update means for buyers
The Pro 5 and Pro 5 Enduro remain attractive to buyers who value Mobvoi’s dual-display design and battery-focused hardware. The software-support trade-off is less certain: the Wear OS 4 rollout was delayed, and this announcement did not define a continuing major-version schedule.

Prioritize Mobvoi when endurance, the low-power display, and rugged hardware matter most. Prioritize a Google or Samsung option when receiving new Wear OS releases promptly is a core requirement. Samsung’s Galaxy Watch7 and Galaxy Watch Ultra were the first Wear OS 5 watches, while Google’s ecosystem page lists Mobvoi products including the TicWatch Atlas, Pro 5 Enduro, and Pro 5: Wear OS device directory. A directory listing is not a future-update guarantee.
Before buying, verify the exact model and region, current app compatibility, phone requirements, availability of services such as Wallet and Maps, and the seller’s live price. Do not buy an older TicWatch solely because it received Wear OS 4; treat that update as a useful feature release, not proof of a strong long-term support record.
The practical verdict
Mobvoi did begin a real Wear OS 4 rollout, but only for the TicWatch Pro 5 and Pro 5 Enduro, and it arrived after Wear OS 5 had been announced and launched on Samsung hardware. Owners should install it with normal backup and compatibility precautions. They should not interpret the rollout as confirmation of Wear OS 5 or any later version.
