CLAW Buckle – Polished
The CLAW Buckle – Polished is the first evolution of the CLAW Strap System, designed to combine the convenience of a classic bracelet clasp with the extreme durability and infinite adjustability of a nylon strap. Designed in the UK, this precision-engineered buckle features a low-profile design that sits very close to the wrist, contoured for comfort and purpose-built for CLAW straps.
This buckle is the result of our experience designing bracelets and infinitely adjustable straps, creating a reliable, secure, and versatile accessory for enthusiasts who demand the best of both worlds.

I’m very impressed with the Sigma CLAW Strap system. The clasp is extremely well made, thin and exudes quality. Admittedly these are supremely comfortable straps, especially the elastic ones. I’ve been using them on a few of my DOXA Sub’s, which aren’t exactly lightweight and these straps control the watch perfectly.
I have posted a video short of the claw strap on my YouTube channel @ MainelyWatches, and will be posting a full review soon.

So pleased, that I just ordered another bundle. Can’t wait for some other widths to become available, and hopefully an expanded color selection of straps. Keep up the good work.
