Five times the battery of the Vantage V3 — enough for week-long mountain stages or ultramarathons without charging access.
Automatically segments your run by uphill and downhill sections, calculating pace and power for each — essential for mountain race training.
Running power without a chest strap or foot pod — Polar's key differentiator versus Garmin at this price tier.
Dual-chip design keeps the main Snapdragon W5 dormant during light tasks, dramatically extending battery life beyond any rival Wear OS watch.
First Wear OS 6 device on the market — with ECG monitoring, EMG gesture control, and eSIM for standalone calling.
Larger and brighter display than Galaxy Watch 8 or Pixel Watch 4, with Hasselblad-tuned health sensors, starting at around $285.
