Perfected for mountain sports

The COROS APEX 4 was designed from the ground up for alpine adventures and demanding trail runs. The high-contrast Memory-in-Pixel display remains clearly legible even in bright sunlight, snow glare, or in the shade. Vertical GPS algorithms, dual-frequency tracking, and a dual-mode altimeter ensure precise navigation in difficult terrain—ideal for rugged mountain ridges. Battery performance is equally impressive: with up to 41 hours in All-Systems GPS mode (42 mm), you’ll remain independent of the power grid even on long routes like the Mont Blanc Circuit or multi-day cross-country treks. Global topographic maps with zero latency instantly show you roads, trails, landscapes, and POIs—including turn-by-turn navigation. Sport modes for trail running, climbing, and ski touring are already built-in, complemented by advanced features for training management, sleep analysis, and recovery and stress assessment. Thanks to a built-in speaker and microphone, the watch also supports you with voice memos, audio prompts, and even hands-free calling. And with two case sizes to choose from, the APEX 4 fits any wrist.
