Key Benefits
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.
Lightweight yet exceptionally durable, it’s precision-engineered for endurance athletes who demand accuracy, reliability, and performance in every environment.
Really enjoy this watch. I was hesitant to get a MIP display but to my surprise it is really good in all light conditions, especially when using the maps and navigation feature, which syncs perfectly with OS Maps. I would highly recommend this product for outdoor enthusiasts
Looks great in an understated way . Mapping and navigation clear and responsive . Easy to use and health and fitness metrics work well as long as heart rate zones accurate
