Leather Selection

IT: Selezione della Pelle - come scegliere il pellame

Definition

Leather selection is perhaps the part of my work that requires the most experience and produces the most significant differences in the final result. Choosing the type of leather isn't enough — you need to choose the right piece of that leather. Every leather is a natural material and as such is variable. Two pieces from the same calfskin, the same tannery, the same batch can have slightly different texture, softness and response to dyeing. The craftsman's task is to recognise these differences before cutting — selecting the piece with the right characteristics for that specific strap. The criteria I use for selection: grain uniformity in the cutting area, absence of natural marks (scars, excessive veining) that could compromise durability, response to flexing, thickness measured with a micrometre in the areas that will bear the most stress (the holes, the stitching, the ends). It isn't a quick process — but it's what separates a strap that lasts twenty years from one that deteriorates after two. For exotic leathers the selection is even more critical. The alligator's belly area has different scales from the back area. The centre of stingray skin has different beads from the edges. Python has scales that vary in size along its length. Every cut is a decision — and every decision has consequences for the finished strap.

Frequently asked questions

How do I recognise quality leather before buying?

By touch even before by sight. A good vegetable-tanned leather has a softness that isn't sponginess — there's structure underneath. By smell, genuine leather has a scent that isn't mistaken for synthetic. When flexed, it doesn't creak and doesn't offer excessive resistance. In raking light, the grain is three-dimensional — not flat like a print. With experience, you learn to tell within a few seconds.

Why can two straps made of the same material be different?

Because leather is a natural material and variability is intrinsic to it. Two pieces from the same calfskin, the same batch, the same tannery can differ in grain, softness, response to dyeing. An experienced craftsman selects the right piece for each strap — not whatever comes to hand. It's part of the job, not a detail.

Can I choose the leather myself for a bespoke Casati Milano strap?

Yes — for Casati bespoke straps, the process starts precisely with selecting the leather together with the client. I show samples, explain the differences, discuss the pairing with the watch. The final choice is always a shared one. I don't impose the material — I suggest it based on years of experience, but the final word belongs to the client who will wear it.

The right strap isn't chosen. It is built, together.
