Rare for a smartwatch with real GPS and health sensors to work fully on both platforms — Versa 4 does.
Turn-by-turn navigation and NFC payments without needing your phone in hand.
Sleep stages, daily readiness score, Active Zone Minutes, and SpO2 — all on a 6-day charge.
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.
The right pick depends on what you optimize for.
$387 vs $749 over 3 years · no required subscription.
40 days vs 6 days battery.
4 sensors.
38g · no required subscription.
Android or iPhone users who want a balanced smartwatch with solid Fitbit health tracking, multi-day battery, and a clean square watch design — without the premium price of a Galaxy Watch or Apple Watch.
Full details →Trail runners, hikers, and outdoor athletes who want Polar's analytics with significantly longer battery life than the Vantage V3. The titanium case and sapphire glass make it suitable for technical terrain where watch durability matters.
