Strap for Royal Oak Ultra Thin Tourbillon White Gold / Japan

No. The bracelet is integrated into the case with a proprietary geometry: a standard strap has no way of attaching. There are no adapters that respect the original proportions. The only option is to build the attachment bespoke, directly on the watch, in the atelier.

I work by appointment only at <a href="/pages/casati-booking">Casati Milano</a>, at Via XX Settembre 15 in Milan. I bring the watch to the bench, take measurements from the actual case and shape every attachment by hand, respecting the transition between the links and the case. There are no templates: each piece is built from scratch on that specific watch.

For a Royal Oak in white gold I prefer brunished Tuscan leather. Its compact structure works well with the architectural solidity of this watch, and it ages developing a dark patina that does not compete with the white gold but accompanies it. Polished Mississippi Alligator is a sound second choice for those who want more visual contrast.

A strap built with first-grade leather and properly cared for easily lasts five, even eight years of daily wear. Care is straightforward: keep it away from prolonged water exposure and condition the leather twice a year with a natural grease. Good leather does not deteriorate — it transforms, and over time it tells a story.

In 1972 Gérald Genta did something precise: he took the industrial hexagonal bolt and brought it into high-end watchmaking. The octagonal bezel with exposed screws and the integrated bracelet are not decorative details — they are the very structure of the object. I have seen many watches on the bench over the years: few have an internal logic as coherent from case to bracelet.
