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.
21 days typical use and 33 hours GPS — combined with a scratch-resistant sapphire glass 1.5" AMOLED that outshines most watches at this price.
Precise dual-frequency L1+L5 GPS across six satellite systems, with downloadable offline topo maps and turn-by-turn navigation — rare at this price tier.
First Amazfit with official HYROX training and competition modes, 40,000-course golf maps, and SCUBA dive support — more sport breadth than any previous Balance.
