Learn how to determine the specific model of your Apple Watch by going to Settings.
Using our list, you can determine which series your Apple Watch belongs to.

Model numbers are quite important and can significantly narrow down a parts search. They are used by manufacturers to identify the parts that were used to create a specific line of products.

It’s also a good idea to know the model number of your Apple Watch in case you decide to sell it. Here’s everything you need to know about Apple Watch model numbers:

Step 1: What Apple Watch do you have by model number

The easiest way to determine which Apple Watch model you have is by finding the model number. You can also use our table to determine the series name and size of each Apple Watch edition.

Open the Apple Watch app on your device (iPhone).
Select “My Watch” and then General.
Select About.
Select “Model”. Tap the number.
After tapping the number, a four-digit number with the letter A will show up. It’s the Apple Watch’s model number.

Step 2: Apple Watch Generations & Model Numbers

The model number indicates which series your Apple Watches belong to. You don’t have to Google search “What series is my Apple watch?” or “How do you know what Apple Watch you have?”

Because model numbers can be used for a variety of styles within a similar series or generation (for example, Hermès models and Nike models), the more unique specifications of the unit will aid you in identifying your Apple Watch model.

Use the table to look up a model number quickly.
