What is my Apple Watch strap compatibility?

Apple Watch comes in a range of sizes. However, the individual dimensions of your device will depend on the model. See our Guide below to match your Watch to the strap size you’ll need!

Apple Watch Series 1 - 38mm or 42mm
Apple Watch Series 2 - 38mm or 42mm
Apple Watch Series 3 - 38mm or 42mm
Apple Watch Series 4 - 40mm or 44mm

Apple Watch Series 6 - 40mm or 44mm
Apple Watch SE - 40mm or 44mm
Apple Watch Series 7 - 41mm or 45mm


What is the difference between "38mm / 40mm / 41mm" & "42mm / 44mm / 45mm" Apple Watch?

If your Apple Watch is a Series 1, 2 or 3, your case size will be either 38mm or 42mm.
If your Apple Watch is a Series 456 or SE your case size will be either 40mm or 44mm.
If your Apple Watch is a Series 7 your case size will be either 41mm or 45mm.


What’s my size?

There are two things to look at when picking a size that's right for you.

Firstly, you want to ensure that it will fit the size of your Apple Watch (the size of your Apple Watch will be stated on the underside of the Apple Watch):

Our 38mm / 40mm / 41mm straps fit 38mm, 40mm & 41mm Apple Watch
Our 42mm / 44mm / 45mm straps fit 42mm, 44mm & 45mm Apple Watch

The next thing is to measure your wrist size:
Some of our straps come in Small, Medium & Large sizes, while others are One Size Fits All.
It's always best to refer to our Size Guide to find the best fit for you.
