Strap for Royal Oak Concept Supersonnerie Platinum The Hour Glass

No. The bracelet is integrated into the case: there is no standard lug to attach an off-the-shelf strap. It is a closed architectural design, conceived that way from the very beginning. If you want to change the strap, the only option is to have one built bespoke, directly on the watch.

I work through <a href="/pages/casati-booking">Casati Milano</a>, my atelier at Via XX Settembre 15 in Milan, by appointment only. I bring the watch to the bench, take measurements from the actual case — not from technical sheets — and build the attachment by hand, shaping every junction until the fit with the case is seamless. There are no shortcuts for a watch like this.

I prefer textured rubber or Mississippi alligator with a matte finish. This Royal Oak has a strongly technical and three-dimensional character: a glossy, formal leather would clash with its architecture. Matte holds the right tone and lets the case do the talking.

A strap built with quality leather and worn with care easily lasts five to seven years. The leather ages — it softens, takes on the creases of your wrist — and that is not a flaw, it is proof that it is genuine. Care is straightforward: keep it away from prolonged water exposure and occasionally apply a neutral leather cream.

In 2002, Audemars Piguet presented the Concept as a visible laboratory: exposed skeletonised bridges, geometries that do not try to conceal the movement but display it as a load-bearing structure. It was not a watch for everyone. It was a statement about where the Le Brassus manufacture wanted to push itself. Every time I have one on the bench, I pause for a moment before I start work.
