To install the developer beta, you must be registered to Apple Developer Program so you can download and install the beta profile on your Apple Watch. This allows you to receive developer beta updates. Note that you cannot downgrade watchOS or restore in case anything goes wrong, so think twice before you install a beta build of watchOS on your Apple Watch. If something goes wrong, you will have to send your Watch to Apple to restore it to a working condition.

If you already have a developer profile installed on your Apple Watch, on your iPhone, go to Watch > General > Software Update and tap Download & Install to upgrade to the new developer beta.
