Find Apple Watch Model from Case

Every Apple Watch has an engraving on the back of the case. This tells you which Series of Apple Watch you’re using, the case material, and the size of the case (in millimeter).

To view the engraving, remove your Apple Watch from your wrist and look at the back of the case.

For example, my Apple Watch’s engraving reads “Series 3, 42mm Aluminium Case, GPS.”

To know if your Apple Watch supports Cellular or not, look at the Digital Crown. If it has a red circle or a red dot on it, you’re using the Cellular model.

You can also learn about the Apple Watch from the model number. Apple has a support page that lists every model number of all Apple Watches.

To find the model number of the Apple Watch that’s paired to your iPhone, first, open the Watch app. From the “My Watch” tab, tap on the “General” option.

Here, go to the “About” section.

Scroll down and locate the “Model” section. It will show a number beginning with “M.” Tap on the listing.

The listing will now change to a number beginning with “A.” This is the model number for your Apple Watch. Take note of it.

Now, open Apple Support’s Apple Watch Identification website.

Here, press “Command+F” on your Mac, “Ctrl+F” on Windows, or use the search functionality on your iPhone or iPad to bring up the search tool and then enter the Apple Watch model number. Complete the search to find the details for your Apple Watch.

If you don’t have access to your Apple Watch, but you can find the model number, use the Apple Watch Identification page to learn more details about your model.
