The EDA (electrodermal activity) sensor tracks physiological stress throughout the day — a feature absent from most competitors at this price.
Comes with Fitbit Premium for advanced sleep analysis, HRV trends, stress management scores, and personalised health insights.
Unlike Apple Watch or Galaxy Watch, Sense 2 pairs with any smartphone and runs 6 days before charging.
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.
