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.
Access the entire watchOS app ecosystem, Apple Pay, Siri, and Family Setup — for $150 less than the Series 11.
Emergency SOS, fall detection, and Crash Detection give real safety value even without premium health sensors.
Available in Midnight, Starlight, Silver, and (PRODUCT)RED with a wide range of Apple Watch-compatible bands.
The right pick depends on what you optimize for.
