Polar M400 GPS Sports Watch & Activity Tracker with Heart Rate Monitor

Polar M400 combines style, performance and comfort. It's an exceptional blend of sporty design, integrated GPS, activity tracking and advanced training features.

Designed for life
Lightweight and compact, M400 is made to be worn all day. Get guidance throughout your training, monitor your activity and get alerts when it's time to get up and move.

Powered by GPS
M400 gives you the freedom to explore new, more adventurous routes: you can measure your pace, distance and altitude and find your way back home.
Training guidance
When you pair your M400 with the H7 heart rate sensor, you'll always know when you're within your target heart rate zone and training at the right intensity (Requires H7 heart rate sensor).

Integrated GPS
Track your speed, distance and altitude with the built-in GPS. M400 also keeps tabs on your personal bests and lets you know when you've set a new record.

24/7 activity
On top of your regular training days, getting enough daily activity is an important part of keeping fit. M400 tracks your steps, calories and sleep time, and notifies you when you are inactive for long periods of time. It also gives you a daily activity goal and tips to reach it.

Running index
Improve your run and more. M400 counts your running index score automatically after every run based on your heart rate and the speed data collected by the built-in GPS (Requires H7 heart rate sensor).
