Start here if the Apple ID can't be remembered --> If you forget your Apple ID or password - Apple Support (IN)
If you can't retrieve the Apple ID, Apple will help you - IF, you are the original buyers of the watch and you can prove original purchase by presenting a copy of the original purchase receipt, which shows the watch's serial number on it.
