I bought a used Apple Watch and it's locked

You must contact the seller (hopefully it is the previous owner), otherwise you have been scammed.

Each Apple device is linked/associated with an Apple ID of the person who did the setup.

Activation Lock prevents anyone who is not the owner from using this Apple Watch.

To unlock the Watch, you need the Apple ID and password of the previous owner, that were used during set up.

So you have to contact the previous owner.

The previous owner has to read -> this Apple article: What to do before you sell, give away, or trade in your Apple Watch, or buy one from someone else

What to do before you sell, give away, or trade in your Apple Watch, or buy one from someone else - Apple Support (IE)

Then the previous owner has to remove the Apple Watch from his account, see this Apple article:

Check your Apple ID device list to see where you're signed in

Check your Apple ID device list to find where you're signed in - Apple Support

Then you can pair the Apple Watch with your iPhone.

See the following Apple articles:

and i dont have his contact information, how i can contact him through email which is written in the apple watch

I need his full email to send him via email because he changed his phone number and I can’t get his number

Apple can't help you, and no one here can help you, we are also users of Apple products & services like you. 

Ask your money back if possible, perhaps you have bought a stolen Apple Watch.

If you can't get in touch with the previous owner / seller, you can't use the Apple Watch, recycle the Apple Watch.

With it having an Activation Lock, there is no way to reset it unless you have your original purchase receipt from Apple or Authorized Apple seller. The same is true for the iPhone. You can't reset the iPhone if it has an Activation Lock on the screen and you are not the original owner. Only the original owner can remove the device from their account in either case.

Unlock my apple watch id

There will be no identifiable information on the watch that will allow you to track it back to the original owner. If you are unable to contact the seller or return the device, then the original owner forgot to reset the device before selling it to you or more likely the device is stolen and the seller who now cannot be contacted was just looking to scam someone by selling them a device that can never be used.

You cannot. The original owner who locked it is the only one who can unlock it.

Buried in all the boilerplate of the first user response above is the fact that Activation Lock prevents lost and stolen Apple devices, in this case an Watch, from being used by others.

M1 Mac mini, macOS 14.5;  Watch, series 7 GPS/cellular, watchOS 10.5; iPhone 12 Pro, iOS 17.5; TV 4th Gen, tvOS 17.5; HomePods, audioOS 17.5 and Airport Express w/ Airplay 2
