Is there a way of finding out the serial number of an Apple Watch that was previously registered to my Apple account?
I recently updated from a series 4 to a series 7 and wiped and removed the series 4 from my Apple account, boxed it up and sold it to a re-seller. They’re claiming it hasn’t arrived and need proof of the watch’s existence by providing the serial number before claiming on insurance.
Is there any way I can retrospectively find out the serial numbers of previously registered devices on my account?
