Your watch might be smart on the inside, but with a Jack Foster strap, it can look just as smart on the outside.

Most smartwatches use a spring-bar attachment that's standard to quality watches. We include a spring-bar tool with every order to help you switch straps, so all you need to do is find the right sizes for your watch model in the table below.

The Apple Watch uses a unique adaptor, which we sew into the strap. We list our Apple straps separately from the standard spring-bar straps, but if you can't find the one you want with the ends you want, please let us know. All of our straps are one-of-a-kind pieces, handmade in the USA.
