Apple Watch Digital Crown scroll doesn't work?

Hi

Operation of the Digital Crown can be affected by substances like dust or lotion. Should it stop operating as expected, it may help to clean it by following the instructions here:

Use the Digital Crown on your Apple Watch - Apple Support

If the issue persists after following the recommended procedure, 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 with a view to arranging for your watch to be inspected and, if recommended, serviced:

• Contact - Official Apple Support
• https://twitter.com/applesupport
• http://www.apple.com/retail/geniusbar/

It may also help to follow these steps:

If you have not yet done so, update your iPhone and Apple Watch to the latest software, starting with your iPhone:

• Update the iOS software on your iPhone, iPad, or iPod touch - Apple Support
• Update the software on your Apple Watch - Apple Support

Restart both your iPhone and your Apple Watch, turning both off together, then restarting your iPhone first:

• Restart your iPhone, iPad, or iPod touch - Apple Support
• Restart your Apple Watch - Apple Support

Unpair and re-pair your watch:

• The Watch app on your iPhone takes a backup of your watch automatically when unpairing via the app. Choose to Restore from Backup during set up. Most data and settings will be restored, with some exceptions (eg Apple Pay cards, passcode).
• Unpair your Apple Watch and iPhone - Apple Support
• Set up your Apple Watch - Apple Supporthttps://support.apple.com/en-gb/HT204568

The procedure applies to all Apple Watch models, including Series 1.
