Vastly better than any other deployant clasps out there. I've tried it all...Octopod, Omega clasp knockoffs from Aliexpress, Artem, Anchor you name it). Much better at a bargain and way easier to fit or change straps.

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.
