BY SERIAL NUMBER
The easiest way to determine exactly which Apple Watch you have is to look up its serial number on Apple’s Check Coverage page. Enter your serial number, and Apple will display the series, model and band size.
Find your serial number on the back of your Apple Watch or in the band slot (you’ll need to remove the band).
Alternatively, you can open the SETTINGS app on your Apple Watch and browse to GENERAL > ABOUT, then scroll down to SERIAL NUMBER.
You can also open the Apple Watch app on your iPhone and browse to MY WATCH > GENERAL > ABOUT, then scroll down to SERIAL NUMBER.
BY ORDER NUMBER
Open the Apple Watch app on your iPhone and browse to MY WATCH > GENERAL > ABOUT. Scroll down to MODEL.
The first number displayed is the order number. It’s more specific than the model number. Reference the following to identify your Apple Watch.
