watchOS 4 was announced by Apple at WWDC 2017 with new features like new Siri, Kaleidoscope and Pixar watch faces, intelligence features, fitness updates, person-to-person Apple Pay payments, and much more. watchOS 4 will be released this fall for all Apple Watch users (1st generation, series 1, and series 2).
You can upgrade your Apple Watch to the developer preview with or without an Apple Developer account. Check out our guide below to find out how.
Before you begin, note that you cannot downgrade Apple Watch to watchOS 3 after upgrading to watchOS 4. Nor can you fix a bricked Apple Watch at home like you can with iOS devices and iTunes. If something goes wrong, you would have to contact Apple Support. If Apple Support in your country supports it, they will take a few days to restore it to the latest non-beta watchOS build. At the time of writing, watchOS 4 beta 6 is the latest version.
Install watchOS 4 on Apple Watch
- Make sure that your Apple Watch is charged at least 50% and placed on the charger. Don’t remove it from the charger throughout this process.

- Once it reboots, open up the Watch app on your iPhone and navigate to General > Software Update. watchOS 4 beta will show up now, ready to download and install.
Follow the steps and grab a cup of coffee because it might take a while. Once done, you should have watchOS 4 running on your Apple Watch.
