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.
Body Battery, sleep coach, training readiness and VO2 max — the metrics Garmin watch owners rely on — in a screen-free band with no mandatory membership.
Swap between a wrist band and an upper-arm band, which many users find more comfortable during sleep and more accurate during workouts.
Up to 10 days between charges, longer than the Fitbit Air's 7 days. A full charge takes up to 90 minutes on Garmin's proprietary charger.
The right pick depends on what you optimize for.
$399 vs $409 over 3 years.
10 days vs 1 days battery.
10 sensors · 0.2 Hz HR sampling.
