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.
The 46mm Apex 4 delivers 65 hours of GPS tracking and 24 days typical use — enough for multi-day mountain events without charging. The 42mm offers 41h GPS and 15 days.
Global topographic maps with instant rendering, turn-by-turn navigation, POIs, and an underwater depth gauge — the Apex 4 is the first COROS mid-tier with a depth sensor.
Audio alerts, hands-free calling, and voice pin recording — a first for the Apex line, adding practical trail and daily-wear convenience to this mountain sports watch.
The right pick depends on what you optimize for.
