• Connect your iPhone to Wi-Fi and launch the Apple Watch app.
• Tap on the My Watch tab.
• Tap on General.
• Tap on Software Update.

• Tap on Download and Install.
• Enter your iPhone Passcode.
• Tap Agree to the Terms and Conditions.

• Make sure your Apple Watch is charged to at least 50% and connect it to the magnetic charger.
• Tap Install on your iPhone and/or your Apple Watch.

The Apple watchOS update will be downloaded and transferred to your Apple Watch and the Apple Watch will reboot to apply the update. You can follow the progress on the Apple Watch screen, and once it’s done, you’ll be all set.

If the watchOS update fails in the verification step. Then try again. If it fails repeatedly. So un-pair and re-pair your Apple Watch and try again. (That un-pairing and the re-pairing process takes a while, so make sure the verification isn’t actually working for you.)

Starting with Apple watchOS 6, Apple added the ability to update your Apple Watch through the Settings app on the Apple Watch itself. While the process isn’t completely iPhone-free yet, it wouldn’t be surprising to see it become so much more during this beta cycle. Here’s how, right now, you can update your Apple Watch through the watch itself.

1. Open Settings on your Apple Watch, either by using Siri or your app list.
2. Tap General.
3. Tap Software Update.
4. Tap Install.
5. Tap OK.
6. Open the Watch app on your iPhone.
7. Agree to the Terms & Conditions while still on your iPhone.
8. On your Apple Watch, tap Download & Install.

Your Apple Watch still needs to be on a charger for the update to install, and it won’t do so until your watch has a battery level of at last 50%.
