M400 is an exceptional blend of sporty design, integrated GPS and advanced training features, along with plenty of options to keep an eye on your activity 24/7.
Push your boundaries and step out of the ordinary. In the Polar Flow service, you can set yourself targets and reach them – in all the sports you do. M400 also keeps tabs on your personal bests and lets you know when you’ve made a new record.
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.
Light, comfortable and water-resistant, M400 is made to be worn all day long – both in and outside your training sessions. Get guidance throughout your workouts, capture your activity and get alerts when it’s time to get up and move.
