Strap for Royal Oak Concept 26577 Supersonnerie Titanium - Ceramic - Pink Gold

The bracelet is integrated into the case: a standard strap simply cannot be attached. The lug is part of the watch's architecture itself, not an interchangeable element. If you want a strap, I build it to measure directly on the watch, at the atelier.

I work exclusively through <a href="/pages/casati-booking">Casati Milano</a>, by appointment only, at Via XX Settembre 15 in Milan. I bring the watch to the bench, take measurements directly from the case with my own tools, and build the attachment by hand — because every geometry in composite materials, titanium, ceramic, and rose gold, demands absolute precision. I do not work from photographs or remotely.

I choose oxidised Barenia. The Royal Oak Concept has a brutal, industrial character, and aged Barenia honours that without softening it: over time it develops a dense patina that speaks honestly to the brushed titanium. As an alternative, Mississippi blue-night alligator picks up the black ceramic and shifts the character towards something more formal — but Barenia remains my clear preference on this watch.

A strap built from quality leather and hand-stitched will comfortably last five to seven years of daily wear — sometimes longer. Care is straightforward: keep it away from prolonged exposure to water, and if it is Barenia, let it age without interfering too much. The leather changes, marks itself, takes the shape of the wrist: that is not deterioration, it is how a good material tells time.

The Concept is not a variant of the classic Royal Oak — it is a separate project, designed to bring the mechanics to the surface and make them legible. The skeletonised case in titanium, ceramic, and rose gold is not decoration; it is the structure of the watch itself, laid bare. I have seen many open-worked movements, but few where the case architecture and the movement tell the same story.
