Apple Watch randomly shuts down after OS 4 update

Since updating my Apple Watch series 2 to watchOS 4, my watch has randomly shut down twice now.  There is plenty of batter left when it happens. In fact, this morning my watch was at 100% when it shut down.

Has anyone else experienced this?

Hi

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

• If any apps on your iPhone have become unresponsive, then force them to close:
  • How to force an app to close on your iPhone, iPad, or iPod touch - 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 (remote diagnostics and/or mail-in service may be available, if required), make a Genius Bar reservation or visit an Apple Authorised Service Provider for assistance, if necessary including to arrange service:
