Which Series or Model Is My Apple Watch? (2023)

What to Know

  • You can find your Apple Watch model by checking the back of your watch or by looking it up in your Apple Watch app on your iPhone. 
  • Once you have your Apple Watch model number, you can check the Apple Watch Generations table below to find which series you own.

Wait, what Apple Watch do I have? Since the different types of Apple Watches look very similar, it can be easy to get confused! Whether you need to know which Apple Watch case or band to order, or you’re planning to upgrade to the Apple Watch Series 8, it’s handy to know how to identify which Apple Watch series you have. I’ll go over how to tell what Apple Watch you have, including the super quick Apple Watch serial number check.

How Do I Know Which Apple Watch I Have?

The Apple model number lookup is the most reliable way to identify which series your Apple Watch belongs to, and it’s quick to find. The only downside is that once you’ve found the model number you have to take an extra step to look up that number in the Apple Watch generations list which I included below to save you time. First, here’s how to find your Apple Watch model number:

  1. On your iPhone, open the Apple Watch app.

  2. Tap the My Watch tab and then tap General.

  3. Tap About.

  4. On this screen, you’ll see a section that says Model. It will contain a number in it, but you'll need to tap this number to reveal the model number.

  5. Once you've tapped on the number, a new four-digit number preceded by the letter A will appear. This is your Apple Watch model number.

You now have the model number but may still be wondering, "What Series is my Apple Watch?" Your model number will tell you which series your Apple Watch is a part of. Use the table below for easy model number lookup! The table will also answer, "What size is my Apple Watch?"

Apple Watch Generations Model Numbers

Use this table to find which Apple Watch series your watch belongs to, and click the links to learn more about each Apple Watch series and its features to help you narrow down exactly which watch you have. Since model numbers may be used across a variety of styles within the same series or generation (e.g. Nike and Hermes), the more specific features and specs of your model will help you determine exactly which Apple Watch you have. This also shows you the Apple Watch Series in order from oldest to newest.
