Hi

The following steps may help:

If your Apple Watch cannot be turned on or restarted normally, then it may help to force restart it:

• How to restart your Apple Watch - Apple Support

Remove any case, bumper or screen protector that may be fitted to your Apple Watch.

Unpair and re-pair your Apple Watch:

• Unpair your Apple Watch and iPhone - Apple Support

If the password cannot be entered on the Apple Watch and/or it cannot be unpaired via the standard process, then it may be possible to erase it manually by following these steps:

• Connect your watch to its charging cable, connected to power.
• Whilst keeping your Apple Watch on the charger:
  • Press and hold the side button until you see the Power Off slider.
  • Press firmly on Power Off (do not try to slide it - just press down more firmly than a normal tap), release your finger, tap on Erase all content and settings and confirm when prompted.
• Re-pair your Apple Watch using the Watch app on your iPhone, choosing to Restore from Backup if offered the option.

If the issue persists or you cannot follow any of those steps, then I suggest that you contact Apple Support (mail-in service may be available, if required), make a Genius Bar reservation or visit an Apple Authorised Service Provider for assistance:
