Strap for Opus 1

No. The bracelet is integrated into the case with a proprietary lug attachment that won't accept conventional straps. I've seen many owners attempt workarounds—I don't recommend it. In the atelier, I build a strap bespoke directly on the case, respecting its original geometry.

We work by appointment only at <a href="/pages/casati-booking">Casati Milano</a>. I take measurements directly from the case, study the lugs, and build the strap from the ground up. It's not an adaptation—it's a second creation, conceived for that specific case.

Mississippi alligator from the Gulf of Mexico. It has the texture and nobility that honour the platinum and mechanics of this watch. It ages with character, developing a patina year after year. For those wanting something more understated, I suggest French Barenia leather—dark, compact, timeless.

Between 7 and 12 years of daily wear, depending on care and intensity. A proper strap in noble leather ages rather than wears out—the creases become history. I recommend keeping it away from excessive moisture and conditioning it every 18-24 months.

Each Opus originates from a collaboration with an independent watchmaker, representing a personal vision of time. A standard strap would contradict that. I build it as an extension of that pursuit: rare leather, craft, precise geometry. It's coherence, not excess.

Yes, I prefer it. <a href="/pages/casati-booking">Book an appointment</a> and we work through the choice together. I want you to feel the material, sense how the leather breathes under your fingers. It's the only way to truly understand what will stay with you for years.
