My 6 month Apple Watch has stopped charging and will not force restart.

Hi

Try the following steps:

Charge your watch for around 2.5 hours, making sure that you follow the charging instructions here:

Check your battery and charge your Apple Watch - Apple Support

After charging, if your watch has not already restarted automatically:

- Try restarting it (by pressing and holding the side button until you see the Apple logo).

- If it still doesn't start, next try force restarting it again: press and hold both the side button and Digital Crown for around 10 seconds, until you see the logo.

If the issue persists, contact Apple Support (mail-in service may be available) or make a Genius Bar reservation with a view to having your watch checked under warranty:

When charging your watch, check that:

• The back of your watch and the head of the charging cable are clean and dry (clean them with a nonabrasive, lint-free cloth).
• The charging head is properly aligned with the back of the watch, with the concave / curved side touching it fully:

  Some watch docks, stands, cases or protectors might hinder this.

• If you are charging your watch by plugging into mains power:
  • Check that the USB connector on the Apple Magnetic Charging Cable is pushed fully into the USB Power Adapter.
  • Check that the USB Power Adapter is fully pushed into the power outlet.
  • Try using different adapters from the following:
    • The genuine Apple USB Power Adapter that was supplied with the watch, or;
    • A genuine Apple 5W (iPhone) or 12W (iPad) USB Power Adapter, or;
    • An Apple-certified (MFi) third-party 5W USB power adapter.
  • Try using a different power outlet (one that is known to be working properly).
  • If no other suitable power adapters are available, try instead charging via a USB port.
• If charging via a USB port on a computer, ensure that you use a USB 2.0 or 3.0 port, the computer remains turned on and awake and the cable is plugged directly into the computer (not into, for example, an external keyboard).
