Restore Apple Watch

If Apple Watch is disabled because you forgot your passcode or entered an incorrect passcode too many times, you can use the Apple Watch app on iPhone to allow you to enter the passcode again. If you still can’t remember your passcode, you can restore Apple Watch and reset the passcode. Restoring erases the content and settings on Apple Watch, but uses a backup to replace your data and settings. For more information, see Update Apple Watch software.
