Apple Watch Series 2 produces high pitched whine.

Hi

Whilst I can't say why that is happening, the following steps may help to prevent the issue from recurring:

• 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 Apple Watch:
  • The Watch app on your iPhone takes a backup of your watch automatically when unpairing via the app.
  • Initially choose to Restore from Backup during set up (most data and settings will be restored, with some exceptions, such as Apple Pay cards, passcode).
  • If the issue persists, consider instead unpairing and setting it up as a new watch.
  • Unpair your Apple Watch and iPhone - Apple Support
  • Set up your Apple Watch - Apple Support

If the issue then persists, 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 having your watch checked and, if recommended, serviced:

• Apple Watch Service Answer Center - Apple Support
