I sold my Apple Watch series 5, the new owner is being asked for my Apple ID to set the Watch up , is there any way he can set it up without my ID

Hey!

One thing you can try to fix this issue is follow these steps:

1. Open settings on your iPhone
2. Click on your name or Apple ID
3. Scroll down until you can see all your Apple devices
4. Make sure that series 5 apple watch is not listed (If it is there, continue following steps, if its not there, skip the next step)
5. Click on the watch, then press "Remove from account"

If you reset the watch fully when you gave it to him and you still don't see the Apple Watch in Apple ID, then I am afraid I am not sure.

If you did remove the watch from the account then give it a shot and see if he still needs it.

Hope this helps,

Cheers

If you truly unpaired the Apple Watch, then it would no longer ask for your Apple ID.

That just happened to me as well my friend gave me their old watch but when he logs into his icloud i t doesnt show the watch as being paired and so i am not sure what is happening.
