I purchased a used Apple Watch and can't unlock it

Make sure that the watch that you're about to buy from someone else is ready for you to use. Click here --> What to do before you sell, give away, or trade in your Apple Watch, or buy one from someone else - Apple Support

This support article has information about Activation Lock on your Apple Watch and how to turn it off as part of preparing a Watch for service or a new owner. --> About Activation Lock on your Apple Watch - Apple Support

- Apple can completely reset a device if a person can provide sufficient evidence of valid ownership. Do this online at: Activation Lock support request - https://al-support.apple.com/#/additional-support Apple says, "Proof of ownership documentation is required," but does not state what currently constitutes proof. Prior to this new online service Apple typically required the original receipt issued by an Apple Authorized dealer and documented provenance (so typically it would be the original owner who does this, or a descendant with legal proof of ownership). Apple recommends you keep your receipt after you buy an Apple device. --> Keep your receipt after you buy an Apple device - Apple Support

If you have neither the information needed to remove the lock, nor a way to prove to Apple's satisfaction that you are the rightful owner, you won't be able to use the Watch.

Sorry to say but you are up the creek without a paddle if the seller has vanished.
