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.

Running power measurement without a foot pod or chest strap — a significant training metric for pacing effort on hills and varied terrain.
