Black and Red Shell Cordovan Strap
SKU: 202-SHLT-COG-20-ST
Cordovan begins with a selection, before it ever becomes a tannage. The shell is a fibrous layer found only in a limited area of the horse’s hindquarters — roughly 30×15 cm per animal. Few hides yield it, and that little requires six months of vegetable tanning before it becomes workable. This explains the price, and explains why it behaves differently from any other leather.
It is not leather in the ordinary sense. It is a compact fibre, almost mineral in its response to time. It does not scratch: it flexes. When a mark forms, the pressure of a thumb is enough to make it disappear — the fibres realign on their own. It is the most wear-resistant material I have worked with: I have cordovan straps that have been in use for ten years and show two.
This strap is made from Shell Cordovan Horween, the Chicago tannery that has worked this leather with methods unchanged for over a century. The colour is cognac — a warmth that, with light and use, deepens further, turning toward dark amber and drawing out that dense sheen which is cordovan’s signature. Not a colour laid on the surface: it is the leather itself maturing. The ecru stitching sits on tone, warm on warm — giving a legible profile without stealing the scene from the colour.
Cordovan does not age. It matures. Every mark of use becomes part of the strap’s character, not a flaw to hide.
Made entirely in Italy. Each piece may show chromatic variations from the images: this is the nature of shell leather, not an imperfection.

The more you wear it, the more it shines.
Shell cordovan doesn’t soften: it compacts. With wear it develops a deep lustre no polish can imitate, and the warmth of your hand tends to close its marks. Leather for a lifetime.

Frequently asked questions
Does cognac stay this way or change?
It changes, and that is the reason to choose it. With light and wear it deepens, turning toward a dark amber, with that dense sheen that is the signature of cordovan. It is not a colour laid on the surface: it is the leather maturing.
What makes shell cordovan different?
It is a fibrous layer found only in a limited area at the rear of the horse, roughly 30×15 cm per animal, and undergoes six months of vegetable tanning before it can be worked. Horween, in Chicago, has been working it since 1905.
Does it scratch?
No: it bends. When a mark forms, a simple press of the thumb makes it disappear — the fibres realign on their own. I have cordovan straps out there for ten years that look like two.
Is a thickness of 2.9 mm too much for a slim watch?
Cordovan is a dense fiber: at 2.9 mm it has body without feeling heavy. The size is 20 mm at the lugs and 16 at the buckle, length 115 × 75 mm.
I have a watch with lugs different from 20mm. Do you make it?
This strap exists only in a 20mm lug width. For a different size, we make it to measure at the Casati atelier, in 4–6 weeks, and you and I define the details together.
