Restore Apple Watch with iPhone Requirements

For this new restore from iPhone feature to work, you'll need:

  • An Apple Watch running watchOS 8.5 or later
  • An iPhone running iOS 15.4 or later

Plus, your iPhone needs to be connected to Wi-Fi with Bluetooth turned on, and the iPhone needs to be unlocked. The Apple Watch needs to be on its charger. Read this article to learn how to update your iPhone software and this article to learn how to update your Apple Watch software. Both products may need to be updated for this to work.

Troubleshooting Restore Apple Watch Not Working

If restoring doesn't work right away, try leaving the Apple Watch on a charger longer to increase the battery level before you try again. If you still experience problems, try using a 2.4GHz network on your iPhone instead of 5GHz. It is also essential to ensure that you are not using a captive or 802.1X network. Public or company Wi-Fi networks may not work to restore your Apple Watch. Try again at home or using a Wi-Fi network that isn't restricted.

Now you know how to restore the firmware on your Apple Watch! Keep in mind that if your Apple Watch isn’t running watchOS 8.5 or later when a firmware issue occurs, you won’t be able to use this method to restore it. This is one of the many reasons why keeping your devices running the latest software is good practice. Sign up for our free Tip of the Day newsletter to learn more about Apple Watch.
