Made for trail running, alpine climbing, ski touring, or any pursuit where endurance meets elevation, the COROS APEX 4 is a high-performance GPS adventure watch built for mountain athletes who want to train hard and go far, fast. Crafted from Grade 5 titanium with sapphire glass and a crystal-clear Memory-In-Pixel display, it’s engineered to perform in extreme conditions — from sun and snow to altitude and impact.
Equipped with dual-frequency satellite tracking, enhanced Vertical GPS algorithms, and a dual-range barometer, the APEX 4 delivers ultra-precise navigation in dense forests, couloirs, and alpine walls. Its next-generation processor provides zero-lag global mapping, displaying detailed topographic and landscape maps with turn-by-turn navigation and named trails.
With up to 65 hours of battery life in Endurance GPS mode(46mm version) and up to 24 days with basic daily use (including sleep, daily stress, and daily HR measurements), the APEX 4 is ready for multi-day missions. Dedicated sport modes for trail running, climbing, and ski touring, alongside advanced training, sleep, and recovery insights, give a full picture of performance.
