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.
21 days typical use and 33 hours GPS — combined with a scratch-resistant sapphire glass 1.5" AMOLED that outshines most watches at this price.
Precise dual-frequency L1+L5 GPS across six satellite systems, with downloadable offline topo maps and turn-by-turn navigation — rare at this price tier.
First Amazfit with official HYROX training and competition modes, 40,000-course golf maps, and SCUBA dive support — more sport breadth than any previous Balance.
