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.
Rare combination: a bright always-on AMOLED display and 14 days of typical use without charging.
Medical-grade ECG and bioelectrical impedance body fat analysis — features usually found only on watches costing $100–$200 more.
