The FKM 20mm Geo Rubber Strap is awesome. High quality and sturdy rubber without being stiff. Has that subtle, cool, almost Clous-de-Paris pattern like a JLC Polaris or classic Calatrava. I'm very happy with it.

Our FKM Rubber Strap — Geo Pattern offers a modern take on a classic rubber band. Crafted from premium FKM fluoro-rubber, it's completely waterproof, flexible, and engineered to handle heat, sweat, and daily wear. The geometric grid texture adds visual depth and improved grip while keeping the strap lightweight and comfortable.
Each strap includes quick-release spring bars for fast, tool-free installation. For certain dive watches, always test spring-bar fit before regular use.

Built From the Best.
A watch strap gets more contact with your skin than almost anything you own. It should be made like it matters. We hand-select leather from tanneries trusted by the world's finest luxury houses — Horween in Chicago, and heritage tanneries across Italy and France. Then we cut, stitch, and finish each strap by hand in our Utah workshop. The stitching, the edges, the feel. Every detail is deliberate, because the watch on your wrist deserves nothing less.

Customer Reviews
Overall rating: 4.5 / 5 from 4 reviews.
This review is for a custom Blue Derby Hudson watch strap with natural edges, 20mm-18mm taper. Now you know what you're looking at. Leather is 2.5mm thick which means that it works well with the Junghans Max Bill Chronoscope as there is very little room at the lugs. It also means that the band is supple and requires no breaking-in. High quality leather and workmanship. Indeed, I am about to order another, Dublin tan to swap out with the blue. My experience ordering/fulfilling this ran into a few snags - computer generated - but beyond the outstanding product, what I really appreciated was/is the humanness of the interaction. It is one thing to purchase something online and everything to be impersonal and anonymous - one's default online experience. However, this was much more like going into a store in a village and greeting the person behind the counter before ordering - as is proper etiquette in pretty much everywhere outside the US. One chats, makes small talk, and in the process of getting the job done has felt beneath it a sense of people who care about their work and doing a good job. Real people. Real products. Something to be valued.
It unfortunately does not fit
