Strap for Constellation Co-Axial 38 Day-Date Stainless Steel / Yellow Gold / Diamond / Silver

No. The bracelet is integrated into the case — there are no standard lugs. A commercial strap won't attach. I build a bespoke solution in the workshop, shaping the new strap directly to your case's geometry.

Come to <a href="/pages/casati-booking">Atelier Casati Milano</a> by appointment. I take measurements directly from your case — width, thickness, angles of the griffes — and craft the strap that fits perfectly. No compromise between the watch and what you'll wear.

Alligator Mississippi. The Constellation has a noble character, and those lateral griffes demand leather that ages with dignity. Alligator develops a deep patina over the years, stays supple and breathes with your skin. It's the strap this watch deserves.

It depends on wear and how you treat it. A well-built strap in quality leather lasts 4–6 years of regular wear. Then the leather ages, perhaps the edge wears. But if you care for it — keep it dry, don't fold it when you're not wearing it — it easily reaches 8–10 years. Fine leather can be repaired, if needed.

They're four talons that embrace the case laterally — since 1952 the defining mark of this collection. Your bespoke strap must respect their exact profile, without touching them, or you lose the architecture Omega built. In the workshop, I measure everything to the millimetre.
