After more than 15 years covering everything Apple, it’s with a heavy heart we announce that we will no longer be publishing new content on iMore and the iMore forums will be closing as of November 1st, 2024.
To restart your Apple Watch, press the side button until you see the option to Power Off your Apple Watch. Wait a minute and restart by pressing the same Side Button and the issue should be solved.
If not, please join our forum and give us some more details on the issue in this thread so we can help you better or contact http://support.apple.com.
The Digital Crown is the one you can turn and press.
