The display of my Polar watch is broken
Worn-out third-party screen protectors can cause problems to the normal operation of your Polar watch's display or make you think that the display of your Polar watch is broken. Please check if the third-party screen protector is causing the problem, before you send your watch to the Polar service. Please remove any third-party screen protector before sending your device in for repair.
Using screen protectors can affect the GPS performance of your watch. We recommend avoiding using them to make sure you get the most accurate GPS data possible.
