    • Before starting repairs, take your watch off the charger and power it down.

    • Use a Tri-point Y00 driver to unfasten the four screws on the back of the watch.

    • Don’t worry about removing the screws, they will stay in place in the back cover.

    I heeded your advice - and now need another screw because it fell out!!!

    I must have stripped the screws out or either the dirt and sweat is so packed into the screw i can't get a good bite to unscrew the screws. What can I do about this? This watch battery DOES NOT hold a charge for more than 5min, should I trash the watch?

    • Insert an opening tool between the back cover and the metal housing.

    • Twist the opening tool to create a wider gap.

    • Don't fully remove the back cover just yet. The sensor flex cable is still connected to the motherboard.
