SKU: 075-TP-GRY-20-ST
Gray calfskin tanned using traditional methods doesn't stay still over time. It moves. It develops amber undertones where the wrist works, a discreet luster where the buckle rests. It's not the flat gray of an industrial surface—it's a breathable shade that gathers light differently depending on the time of day and the season.
Six months after purchase, the leather already has a story. Two years later, it's completely yours. This is the mechanism of traditional tanning: it favors a natural patina that evolves elegantly, without dramatic changes. The gray remains gray—but it becomes your gray.
On the wrist, it works with any case: steel, gold, titanium, bronze. With light or dark dials. With a Datejust in the office and a Black Bay on the weekend. It's the strap collectors keep as a universal reserve—and it ends up becoming their favorite.
The hand-stitching with waxed thread is only visible up close. As it should be.

It starts firm and, week after week, takes the shape of your wrist. The surface grows warmer to the touch, the colour gains depth where the light hits it. No plastic on top: leather that ages honestly.

Every strap has integrated quick-release spring bars: swap it in one gesture, no tools, no risk of scratching the lugs. The same watch shifts mood with the moment.
Chosen for you
The tanning is traditional, not industrial. The wrist warms the leather, and that is where amber undertones develop, along with more sheen near the buckle. At six months you can already notice something. At two years it is a different grey from the starting one, but it stays grey: just more its own.
Three: 20mm x 16mm, 22mm x 18mm, 24mm x 20mm. The length is fixed, 115mm on the case side and 75mm on the buckle side, with a thickness of 2.5mm across all sizes.
Yes. I also fit it on Omega Constellation, Seamaster, Patek Calatrava, IWC Portofino, Cartier Santos, Tudor Black Bay. Standard lugs, it works on dress watches and tool watches alike.
Steel, gold-plated yellow gold, gold-plated rose gold, black PVD. You will find all of them available on every size, from 20mm to 24mm.
Yes, hand-stitched with waxed thread. Up close you can see it, from a distance you can't: that's how it should be, not just a showcase effect.
