| Next model | — | Apple Watch Series 12 (Expected fall 2026) |
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 Series 11 is the first mainstream smartwatch to offer FDA-cleared hypertension (high blood pressure) detection — a feature that could flag silent health risks.
At 9.7mm, the Series 11 is significantly slimmer than previous models — noticeably lighter on the wrist for all-day and sleep tracking.
On-demand ECG, continuous blood oxygen monitoring, and sleep apnea detection (FDA-cleared) make this one of the most medically relevant consumer wearables available.
The right pick depends on what you optimize for.
