How to hard reset your Apple Watch

1. Position the Watch so you can easily access both the Digital Crown/Home and Side buttons, and then firmly hold the device in your hand.
2. Simultaneously press and hold both buttons for roughly 10 seconds, until the screen turns off and the Watch reboots.
3. Voila! You're good to go.

Hi friend,

try to force a restart or try to reset the watch.

Stay safe. Take care.
