The new health sensing system samples heart rate every five seconds all day — 60x more often than the Series 11 — and measures HRV every five minutes.
A daily 0–10 readiness score combines sleep, vitals, training load, and activity to suggest how hard to push.
On-demand ECG, blood oxygen monitoring, sleep apnea detection, and hypertension notifications carry over from the Series 11.
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, built into the watch.
The right pick depends on what you optimize for.
