Iwatch Problem

Hi

Try force restarting your watch: press and hold both the side button and Digital Crown for around 10 seconds, until you see the Apple logo, then release them and wait for the watch to restart.

If that does not immediately resolve the issue, try charging your watch for around 2.5 hours.

If it has not restarted automatically after that time, try restarting - or, if necessary, force restarting - it afterwards:

You're welcome! 🙂
