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.
