Premium Build Quality

Being able to transition from the workplace, into your training element is made much easier with the quality build and design. Sourcing the best materials, the APEX includes a titanium alloy and ceramic bezel finish, complete with a sapphire glass for extreme protection.

Your Complete Training Guide

Based on a unique algorithm with lactate threshold, the COROS Trainer dials-in your running training every day. It will be split-up into three different stages: Warm Up, Training, and Cool Down. The COROS Trainer will then provide the duration and target heart rate throughout each stage. This is available for both Aerobic and Anaerobic Training modes.

Training Efficiency Without Injury

To prevent injury, there’s nothing more crucial than training correctly. We’re able to accurately determine your overall effort, broken down into stamina level (0-100) and training effect (0-6). Exerted way too much stamina? COROS Trainer will notify you it’s time to rest up. Based on the effort level and training history, you will then be able to see an advised recovery window before you begin your next activity. This is available for Interval, Aerobic, and Anaerobic Training modes.

Simplicity at its Finest

Using buttons to change screens can be overwhelming at times, especially in the middle of a workout. With the digital knob, you can easily navigate through the APEX inside and out with a single turn of the knob by using only a single finger.

Advanced Training Analysis

Once you’ve finished your workout, the best part begins. Our COROS App will give you a complete graphical analysis of your training – including: VO2 max, recovery advisor, threshold pace, last-7 days training load, personal fitness index and plenty more.

Additionally, you can connect to your favorite 3rd party applications such as STRAVA and TrainingPeaks and automatically upload your workouts.

Navigation Track

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.

Smart Learning Stryd Length

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).

Customise Your Look

Easily swap-in and out the premium silicone watch band to a color or material that matches your personality. Not to mention, our watch band will also sit comfortably on your wrist, allowing for more accurate heart rate readings.

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 (varies depending on model).
