Which is right for you?
Choose the Garmin Forerunner 965 if you want more smartwatch features
The Forerunner 965 combines multisport tracking with Garmin’s broader smartwatch package, including music storage, contactless payments, and Garmin’s training features. Garmin lists built-in mapping and Training Readiness among its capabilities. It is a strong fit if you want training guidance and an integrated route-and-map workflow alongside everyday features.
Garmin’s system presents a range of training information and guidance. Consider whether you want those prompts and metrics as part of your routine, rather than assuming a readiness score should determine whether you train.
#1 Best Overall
- Brilliant AMOLED touchscreen display with traditional button controls and lightweight titanium bezel
- Battery life: up to 23 days of battery life in smartwatch mode, up to 31 hours in GPS mode
- Confidently run any route using full-color, built-in maps and multi-band GPS
- Training readiness score is based on sleep quality, recovery, training load and HRV status to determine if you’re primed to go hard and reap the rewards (data presented is intended to be a close estimation of metrics tracked)
- Plan race strategy with personalized daily suggested workouts based on the race and course that you input into the Garmin Connect app and then view the race widget on your watch; daily suggested workouts adapt after every run to match performance and recovery
Choose the Polar Vantage V3 if you value recovery tools and health sensors
The Vantage V3 combines Polar’s training and recovery features with wrist ECG and nightly skin-temperature sensing, as described on Polar’s product page. Its tools include FitSpark, Running Program, FuelWise, Training Load Pro, and Running Index. It may suit athletes who prefer Polar Flow’s self-coaching approach and want those additional sensors.
These are sports-watch wellness features, not substitutes for medical evaluation. The comparison review also cautions against treating either watch’s wellness measurements as serious medical insight.

Training, tracking, and navigation
Both watches provide AMOLED touchscreens, dual-band or dual-frequency GNSS, mapping, and multisport training functions. In its April 25, 2024 comparison, Wareable found strong dual-band tracking from both watches, but reported that both slightly overestimated distance in its marathon test. That is a review finding, not a guarantee of how either watch will perform for every runner or route.
The same Wareable review judged Garmin’s map use and training-data presentation more polished. It praised Polar’s sleep insights and noted the Vantage V3’s ECG and skin-temperature sensors. These are the reviewer’s observations from April 2024, not current hands-on testing for this article. The review also found Polar’s FitSpark used workout history, while Garmin’s training-plan experience and presentation felt more polished.

Check current software and route workflows before choosing based on these details.
Battery life and price
Garmin’s official US comparison page lists up to 23 days in smartwatch mode. Polar’s technical specification lists up to 42 hours in dual-frequency performance training mode, up to 110 hours in eco training mode, and up to 11 days in smartwatch mode with continuous heart rate and notifications enabled. Since the brands specify different modes and conditions, these figures do not establish which watch will last longer in your personal use.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Heart-rate accuracy
Both watches can pair with external heart-rate sensors, according to Wareable’s comparison. The review recommended an external monitor for readers who particularly prioritize heart-rate accuracy, and its tested examples included the Garmin HRM-Pro Plus and Polar H10. Check current compatibility before purchasing an accessory. Wrist-based wellness and heart-rate readings should not be treated as medical measurements.
Verdict
Pick the Garmin Forerunner 965 if Garmin’s integrated mapping workflow, Training Readiness and other training guidance, music storage, and payments best match your priorities. Pick the Polar Vantage V3 if Polar’s training and recovery tools, wrist ECG, and skin-temperature sensing matter more to you. Compare current prices and confirm any navigation or connectivity feature that is essential to your use before buying.

FAQ
Do the Forerunner 965 and Vantage V3 both have maps?
Yes. Both offer mapping. Wareable’s April 2024 comparison judged Garmin’s mapping experience more polished, but its comments about Polar’s map-transfer process and turn guidance reflect that review period and may not describe current software.
Which watch has longer battery life?
The published figures are not directly comparable because the modes and conditions differ. Garmin lists up to 23 days in smartwatch mode. Polar lists up to 11 days in smartwatch mode with continuous heart rate and notifications enabled, and up to 42 hours in dual-frequency performance training mode. Always-on display use drains battery faster, according to Polar’s technical specification.
Does the Polar Vantage V3 have ECG and skin-temperature sensing?
Yes. Polar’s product information lists wrist ECG and nightly skin-temperature sensing alongside features such as SpO2, maps, and dual-frequency GPS. These sports-watch features are not a replacement for medical advice.
