How to Find Your Apple Watch Model Number
The Apple model number 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 lists. Not to worry; I’ve consolidated those below to save you time. First, here’s how to find your Apple Watch model number:
- On your iPhone, open the Apple Watch app.
![]()
- Tap the My Watch tab and then tap General.
![]()
- Tap About.
![]()
- 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.
![apple watch model number]()
- 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.

Your model number will tell you which series your Apple Watch is a part of. Use the table below for easy model number lookup!
