Polar Vantage V3 is one of the few sports GPS watches with on-demand ECG — usually only found on lifestyle smartwatches.
Running power measurement without a foot pod or chest strap — a significant training metric for pacing effort on hills and varied terrain.
The most detailed training load analysis in any sports watch: muscle groups targeted per session, recovery status per muscle, and long-term load trends.
The Ultra 3 nearly doubles the Series 11 battery life, and satellite emergency SOS works even without cellular or WiFi coverage.
More precise GPS tracking in urban canyons and dense forests — critical for trail running, mountaineering, and triathlon.
The 49mm titanium case and 3000-nit display make this watch usable in full direct sunlight and water depths up to 100m (EN13319 certified for diving).
