"Update your Apple Watch using your iPhone

You can wait until Apple Watch notifies you when a new update is available. Tap Update Tonight in the notification, then go to your iPhone to confirm that you want to update overnight. At the end of the day, leave your Apple Watch and iPhone charging overnight so the update can complete.

Or you can update your Apple Watch with your iPhone manually:

1. On your iPhone, open the Apple Watch app, then tap the My Watch tab. 
2. Tap General > Software Update.
3. Download the update. If asked for your iPhone passcode or Apple Watch passcode, enter it. 
4. Wait for the progress wheel to appear on your Apple Watch. It could take from several minutes to an hour for the update to complete. "

Let us know if you have further questions.

Take care.
