In this guide, the wrist band of the Polar V800 is removed for a clear view of the back panel. If you find it helpful, you may want to remove the wrist strap. Please reference the Watch Band Replacement guide for removal instructions if you wish to do so.
Ensure your Polar V800 sports watch is powered off before continuing.
Remove the eight, 7.4 millimeter-long screws on the back of the watch with a T5 head-type, torque screwdriver.
Gently separate the watch housing from the back panel.
The watch should come apart easily after removing the screws. If you experience difficulties separating the housing and and back cover, use a spudger to gently pry apart the back panel and the button and screen protector housing.
