The Polar M400 GPS Running Watch and Activity Tracker is a GPS watch that monitors your workouts and daily activity. It’s first and foremost a running watch, but it can also be used for activities such as cycling, CrossFit training and even horseback riding. The device collects lots of data: calories burned, steps walked, personal records, and more. All data is viewable directly on the watch screen. The Polar M400 shows you the percentage of your daily activity goals you’ve completed and offers a practical guide to reach those goals. It syncs via Bluetooth or USB to your smartphone or computer. Battery life is eight hours in GPS mode and 24 days in activity mode.
