Strap for Royal Oak 37 Double Balance Wheel Openworked Frosted Yellow Gold / Rainbow

No. The bracelet is integrated into the case: there is no standard lug to attach an off-the-shelf strap. The attachment is proprietary, part of the octagonal geometry Genta designed. If you want to wear it on leather, I build it bespoke, directly on the watch at the atelier.

I work by appointment only, at <a href="/pages/casati-booking">Casati Milano</a>, Via XX Settembre 15, Milan. I bring the watch to the bench, take measurements directly from the case, and shape the attachment by hand until it sits flush with the original geometry. There is no form to fill in remotely: I look at the watch in person.

For a yellow gold Royal Oak I prefer natural honey-toned Barenia: it ages alongside the watch and reflects the warm tones of the gold without mimicking them. A close second is large-scale Mississippi alligator, whose firm texture holds its own against the octagonal case. I would avoid anything too dark or sporty — this watch calls for quiet, considered elegance.

With reasonable care — keeping it away from water, letting it breathe, and occasionally conditioning it with a neutral cream — a Barenia or alligator strap will comfortably reach five to seven years. Quality leather does not deteriorate; it transforms. The first creases at the wrist are the strap adapting to you, not falling apart.

In 1972, Gérald Genta did something nobody had attempted: he brought steel into haute horology with an octagonal case and exposed screws — elements considered industrial at the time. Over the years I have seen many watches come through, and that design coherence — every component serving the structure — is genuinely rare. This yellow gold version carries the same architecture in an entirely different material, without betraying the original character.
