Not sure which size band you need to purchase? We're here to help.

First, it's important to know which size of Apple Watch™ you own, either 38mm or 42mm. If you're unsure, this information can be found etched on the back of your Apple Watch™, in the ring of text that surrounds the heart rate sensor on the back of the watch. Your model size can also be found from launching the Watch app on your iPhone, as can be seen here.

Next, you need to choose your desired band length. We offer two lengths, small and large. The size you choose is up to personal preference to what best fits your wrist. If you currently own an Apple Sport band, our small length strap is similar in size to Apple's S/M band length. Likewise, our large length band is similar in size to Apple's M/L band length. If you're unsure as to which size you use, Apple's Sport bands have their size printed on the back of the band toward the end of the strap, near the connector lugs. If you're still unsure, we advise that you see Apple's sizing guide, or contact us directly.
