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. 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. 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.Introducing COROS' very own, Intelligent Stride Algorithm. This unique algorithm embodies machine learning at its core to record your personal range of motion while running. This will build your very own stride model that will be used for indoor running or areas of weak GPS signal (such as tunnels). Equipped with track and navigation features, APEX can be your best tool when you need directions the most. Routes are uploaded and displayed on grid as a bread crumb trail with real time information on heading and elevation and alerts to help you get back on course.Supported Workouts: Run, Indoor Run, Trail Run, Track Run, Mountain Climb, Hike, Bike, Indoor Bike, Pool Swim, Open Water, Triathlon, Gym Cardio, GPS Cardio, Ski, Snowboard, XC Ski, Ski Touring, Multisport, Strength, Training.
