Strap for Opus 4

No, the bracelet is integrated into the case — there are no standard spring bars. A conventional strap won't attach. What I do in the atelier is build a bespoke strap directly onto the case, studying the geometry of the platinum.

We work only at <a href="/pages/casati-booking">Casati Milano</a>, by appointment. I take the watch in hand, study where the case meets the wrist, and build the strap following that precise geometry. It's an adaptation, not an application.

I prefer Mississippi Alligator for the Opus. Platinum has an almost austere geometric precision — a leather with marked but controlled grain keeps that intellectual character without competing with the case. Alligator ages beautifully, and its thickness supports the weight of the piece.

With quality leather and proper care, it lasts 5-8 years of daily wear. Leather isn't a countdown — it depends on how you treat it. Alligator, which I favour for this model, becomes softer and deeper over the years. Occasional cleaning and avoiding excess moisture make all the difference.

Harry Winston chose platinum because it's the metal of zero compromise — it's heavy, inert, demanding to work. It's not an aesthetic choice, it's a statement: form follows mechanical complexity, nothing more. Platinum tells what craftsmanship requires, nothing less.
