Apple Watch Size Question

What is My Apple Watch Band Size?

All bands for 38mm, 40mm, and 41mm Apple Watch models are interchangeable. Similarly, bands for the 42mm, 44mm, and 45mm models can be used interchangeably.


The 49mm size is unique to the Apple Watch Ultra, which features a distinct case design and band attachment system due to its larger and more rugged build.

Fortunately, Apple has engineered the Ultra to be compatible with bands from the 42mm, 44mm, and 45mm models. This means you can use your existing 45mm bands with the 49mm Ultra, offering flexibility in your band choices.

Please note that while the bands may fit, there might be slight differences in design and aesthetics due to the Ultra's distinctive design.

For more detailed information, you can visit the Apple Watch official page. Once you know your size, explore our selection of bands at Burnana Concept.

 

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.
