Strap for Opus 3

No, the bracelet is integrated into the case. The attachment has a proprietary geometry that won't accept conventional straps. But that's not a limitation — in the atelier, I build the strap directly onto your watch, modelling the interface bespoke. It's the only honest approach for a watch like this.

We work exclusively at <a href="/pages/casati-booking">Casati Milano</a>, by appointment only. I take measurements directly from the case, study the attachment millimetre by millimetre, and build the strap from scratch for your specific watch. It's not mass production: it's pure craftsmanship.

I recommend alligator or African crocodile leather, with minimal finishing. An Opus breathes geometry and radicality: the leather must be restrained, with natural grain that tells the story of time. No gilding, no excess. The subtle patina that forms over the years is the true beauty.

It depends on use and care. With mindful maintenance — keeping it away from stagnant water, letting it breathe — it easily lasts 6–8 years. The leather ages nobly, creases deepen, the texture softens. After that, you restore it: with fresh leather, the strap is as good as new.

Yes, absolutely. An Opus is born from a conceptual vision by its creator; every curve, every proportion has meaning. A generic strap betrays that coherence. That's why I insist: we study the case geometry together, choose leather that speaks the language of the watch, and build it with you.
