Hi

The following steps may help:

• Check that Bluetooth and Wi-Fi are enabled on your iPhone:
  • Settings > Bluetooth.
  • Settings > Wi-Fi.

• Restart both your iPhone and your 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

If the issue persists, next 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 Support

If you cannot unpair your watch via the Watch app on your iPhone and you cannot access your watch, instead follow these steps to erase it before re-pairing:

• Connect your watch to its charging cable, with power connected.
• Press and hold the side button until you see the Power Off slider.
• Press firmly on Power Off (do not try to slide it - just press down more firmly than a normal tap) and then tap on Erase all content and settings.
• Re-pair your watch using the Watch app on your iPhone, choosing to Restore from Backup if offered the option.
