    Ultra-Durable Battery Life

    Make constantly charging your watch a thing of the past. With APEX, you will have a watch that is built to last above and beyond your workout. In UltraMax setting, the battery is carefully engineered to last up to 100 hours using GPS. While using normal mode will yield up to 35 hours, and regular usage up to 30 days.

    Built in Premium

    Transitioning from the workplace to training is easy with the APEX's intelligent build and design. With finish options including titanium alloy and stainless steel bezel alongside a sapphire glass face for extreme protection, you are prepared for any and every environment.

    Simplicity at its Finest

    Changing screens and using devices can be overwhelming with traditional buttons, especially in the middle of a workout. With the digital dial, you can easily navigate through the APEX, allowing you to focus on the important things like finishing your run or prepping your next set.

    GIF of track run mode

    A standard track is 400m, so why can’t GPS devices seem to get it right? With the new Track Run Mode from COROS, a proprietary algorithm, is used to make sure your track runs and workouts are measured accurately regardless of which lane you choose. Gone are the random zigzags across the field, or sharp angled turns, replaced with the smooth straightaways and curves of the track – just like how you run on it.

    • The Apex is good looking, built to last, has a bomber battery life, and a long list of features specifically targeting endurance athletes and mountaineers. Whether you're an ultra runner, ironman, recreational runner, or mountaineer, this watch will keep up with you and accompany you seamlessly into the office.

    • Should you buy it? Yes, the Coros Apex is a solid performing fitness watch for those who run, cycle, or swim. Its extra-long battery life is unrivaled for its size, making it a great choice for endurance athletes.

    • When power matters, grab the Coros Apex. We tried to kill the battery, but like Michael Myers or Jason Voorhees, it wouldn’t die. A two-hour run knocked only 5 percent off the charge, and it can go all week without having to give it juice.

    • As I’ve stated, the design and functionality in both the watch and its app are as close to perfect as I could find in a watch.
