Q: Apple watch -

Hi

The following steps may help:

• 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

• On your iPhone, go to: Settings > General > Keyboard:
  • Check that Enable Dictation is turned on.

• On your iPhone, go to: Settings > Siri - disable, pause for a few moments and then re-enable Siri.

• Restart both your iPhone and your watch, turning both devices 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 when offered the option 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 Support
