Apple Watch Setup
I put in the right old Apple ID for the security or whatever to set up my Apple Watch but it’s saying it’s not the right Apple ID but it was only ever paired to that Apple ID what do I do?
Question marked as
Sign in to the Find My page on iCloud with that same Apple ID. Is your watch showing up there?
If not, clearly some other Apple ID has been used. Do you still have your old iPhone so you could doublecheck it there? Apple Watch gets that ID from the paired iPhone.
