EASIEST METHOD

Find the Model Number Using Your iPhone.

If your Apple Watch is paired with an iPhone, you can find the identifying model number directly inside the Watch app.

1
Open the Watch App

On the iPhone paired with your Apple Watch, open the Apple Watch app.

2
Tap My Watch → General

Open the My Watch tab and select General.

3
Tap About

Select About to view information about the paired Apple Watch.

4
Find the Model Field

The field may initially show a part number beginning with the letter M. Tap it once.

5
Look for the A-Number

After tapping the field, it should change to a model number beginning with A. Use that number to identify the watch.

MODEL NUMBER VS PART NUMBER

M-Number? A-Number? Here’s the Difference.

The Model field can display different identifiers. For identifying the Apple Watch family, the A-number is generally the most useful one.

M

Part Number

The value initially displayed in the Model field may begin with the letter M. This is the device’s part number.

A

Model Number

Tap the Model field and it changes to a number beginning with A. This is the model number used to identify your Apple Watch.

Match It With Apple

Apple’s identification guide maps A-numbers to the applicable Apple Watch generation, size and regional configuration.

NO IPHONE HANDY?

Check the Back of Your Apple Watch.

The engraving around the back of your Apple Watch can provide additional information that helps narrow down which model you have.

  • Apple Watch family or series information
  • Case size in millimetres
  • Case material
  • GPS or Cellular characteristics on applicable models

The exact information engraved on the watch varies by generation, so use it together with the A-number whenever possible.

GPS or GPS + Cellular?

Connectivity is another useful detail when confirming an Apple Watch configuration.

GPS

GPS Models

GPS-only and GPS + Cellular versions can have different model numbers even when they belong to the same Apple Watch generation and case size.

GPS + CELLULAR

Cellular Models

Many Cellular Apple Watch models can also be visually distinguished by a red accent on the Digital Crown, although the exact design varies between generations.

ALWAYS CURRENT

Match Your Number With Apple’s Current Model List.

Apple continues to release new Watch models, so rather than relying on an old static list, use Apple’s current identification guide to match your A-number to the exact model.
