To identify your Apple Watch, reveal its A-number in the paired iPhone’s Apple Watch app, then match the complete number and its region on Apple’s official identification page. Apple’s page maps model numbers to watch families and GPS or GPS + Cellular variants; check the engraving on the back of the watch to confirm its case size.
Apple Watch model lookup at a glance
| What to check | Where to check it | What it tells you |
|---|---|---|
| A-number | Apple Watch app on the paired iPhone | Use Apple’s model list to identify the family and connectivity variant. |
| Region | Apple’s listing for the matching A-number | Some models have different numbers by sales region. |
| Case size | Engraving on the back of the watch | Confirms the case size; do not infer it from the family name alone. |
How to find and match your Apple Watch model number
- On the paired iPhone, open the Apple Watch app.
- Tap My Watch, then General, then About.
- Tap the value beside Model Number. Apple says it changes to a number beginning with “A.”
- Compare the complete A-number with the relevant family, connectivity variant, and region on Apple’s identification page.
- Check the engraving on the back of the watch for its case size and additional information.
What the model number can tell you
Apple organizes its identification page by generation and variant, including GPS and GPS + Cellular where applicable. Some models have different A-numbers for different sales regions, so compare the full number with the appropriate regional listing rather than assuming one number applies everywhere.
The A-number is a way to match the watch to Apple’s listed model. Appearance, case material, and special-edition branding should not replace that match. For bands or other accessories, check the seller’s stated compatibility for your specific case size and watch generation; a size match alone does not establish that every band will fit.
Examples of Apple Watch case sizes
| Family | Case size listed by Apple | Connectivity note |
|---|---|---|
| Apple Watch Series 11 | 42 mm and 46 mm | GPS and GPS + Cellular variants are listed. |
| Apple Watch SE 3 | 40 mm and 44 mm | GPS and GPS + Cellular variants have separate model numbers. |
| Apple Watch Ultra 3 | 49 mm | Listed as GPS + Cellular. |
These are examples from Apple’s identification page, not a complete list of every model. Apple’s page also lists newer families, including Series 12 and Ultra 4, as well as older models. Check the live page for the current model numbers and entries.
