Hi

If your Apple Watch cannot be unlocked via the normal process, then follow these steps to erase it and re-pair it with your iPhone:

• Connect the Apple Watch to its charging cable, connected to power.
• Whilst keeping the Apple Watch on the charger and connected to power:
  • 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), release your finger and then tap on Erase all content and settings and confirm.
• Re-pair your Apple Watch using the Watch app on your iPhone, choosing to Restore from Backup if offered the option.
