Selling my 9 month old Polar M400 since I am upgrading to a different watch. The watch is in good condition, works perfectly and has a great battery life.

The Polar M400 is a GPS running watch but also has 24/7 activity/sleep tracking features. It can display notifications from an iPhone or Android device as well. Also has the capability to be paired with a bluetooth heart rate monitor, stride sensor if required.

Message me if you are interested in having a look. Can meet on campus.
