Expert opinion
Vantage M3 shares the Vantage V3’s processor, GNSS chipset, Elixir Gen 4 sensor and full software feature set, in a 44.7mm case that weighs 53g with strap against the V3’s 57g. The reduction in size costs battery: 30 hours in performance training mode against the V3’s 43 hours, from a 310mAh cell against the V3’s 488mAh.
It carries ECG, SpO2 and skin temperature sensors, a barometer and compass, and offline TOPO maps, the full physiological sensor suite that Polar’s fitness-tier Ignite 3 and Pacer models lack. Navigation is limited to breadcrumb trails and imported routes. Polar retired its on-device route creation tool, Explore, in 2020, and there is no on-watch re-routing.
What’s new versus the Vantage M2
Hardware
- 1.28-inch AMOLED touchscreen with Gorilla Glass 3, up from a 1.2-inch MIP display
- Elixir Gen 4 sensor with ECG, SpO2 and nightly skin temperature
- Dual-frequency GNSS chipset and revised antenna design
- Barometer and magnetic compass
- Water resistance to 50m, up from 30m
- Offline TOPO maps for Europe and North America
- Faster processor at 275MHz, with 37MB memory and 32GB storage
- Operating range extended to -20°C to +50°C
- Factory-replaceable battery
Software
- Wrist-based running power
- Voice guidance
- Work-Rest Guide
- Vertical speed and VAM (ascent speed)

Battery life fell in two of three modes despite the hardware upgrade. Eco training mode dropped from 127 hours on the M2 to 70 hours, and smartwatch mode from 8 days to 7. Performance training mode rose from 26 to 30 hours. The AMOLED display accounts for the difference.
