Strap for Royal Oak Concept 26577 Supersonnerie

No. The bracelet is integrated into the case: there are no standard lugs to attach an off-the-shelf strap. The attachment is proprietary, with complex geometries in titanium and ceramic. The only option is to build a bespoke strap directly on the watch, in the atelier.

I work exclusively by appointment at <a href="/pages/casati-booking">Casati Milano</a>, at Via XX Settembre 15 in Milan. You bring the watch: I take measurements from the actual case, not from a data sheet. Every attachment is shaped by hand to follow the curves of the case. The result is a strap born from that specific watch and no other.

For a watch with this character — titanium, ceramic, visible movement, a declared technical soul — I choose naturally aged Barenia. Its compact texture holds its own against industrial materials without mimicking them. It ages with wear, developing a personal patina. It is the leather that, over time, tells the story of who wears it.

With quality leather and minimal care, I count on at least five to seven years of daily use. Simply keep it away from prolonged water exposure and let it breathe between wearings. Barenia and alligator do not deteriorate: they transform. That transformation, for me, is the sign that the work was done properly.

The Concept is not a variant of the classic Royal Oak: it is a research laboratory worn on the wrist. The titanium and ceramic case is not an aesthetic choice — it is a technical statement. The movement is visible not for decoration, but because the watch has nothing to hide. I have seen very few watches with this consistency between form and intention.
