What you need

Steps

  1. Put your Apple Watch on its charger and keep it there for the whole update. The watch needs at least 50 percent battery and must stay powered.

  2. Restart the Apple Watch. Press and hold the side button, then drag the Power Off slider. Press and hold the side button again to turn it back on.

  3. On the iPhone, open the Watch app and tap General, then Software Update. Check whether a newer watchOS version is listed.

  4. Connect both the iPhone and the Apple Watch to the same Wi-Fi network. On the watch, open Settings, tap Wi-Fi, and pick your network.

  5. Keep the iPhone close to the watch and leave both screens unlocked. Do not open other apps while the update downloads.

  6. Start the update again from the Watch app and wait. If the watch shows the Apple logo with a progress bar, leave it alone until it finishes.

  7. If the error returns, unpair the watch in the Watch app, then pair it again and restore from your backup.

Tips and common mistakes

Charge the watch fully before you start, since a low battery is a common cause of failed updates.

Use a 2.4 GHz Wi-Fi network if the 5 GHz one keeps dropping during the download.

Never force restart the watch while the Apple logo and progress bar are showing, as that can corrupt the update.

Questions

Why does my Apple Watch say unable to install update?

Usually the watch has too little battery, a weak Wi-Fi connection, or not enough free storage. Charging it and joining a stable network fixes most cases.

How long should a watchOS update take?

Plan for 30 to 60 minutes including the download. Keep the watch on its charger and the iPhone nearby the whole time.

Will unpairing erase my Apple Watch?

Unpairing removes the data from the watch, but a backup is saved on your iPhone. You can restore it when you pair the watch again.
