Strap for Royal Oak Perpetual Calendar 41 Ceramic Only Watch 2017

Not in the conventional sense. The bracelet is integrated into the case with a proprietary attachment: a standard strap simply cannot connect. The only option is to have one built to measure, 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 take measurements from the actual case at the bench — not from a datasheet. Every lug is shaped by hand to respect the geometry of the ceramic case.

I would choose black gloss Mississippi alligator, without hesitation. The black ceramic has a hard, cold surface — it calls for a leather that speaks the same language, compact and with deep reflections. Contrast would be wrong here; continuity is everything.

With basic care — keeping it away from water, letting it breathe — a well-built alligator strap lasts five, sometimes eight years. The leather changes over time: it softens and develops a patina that tells the story of use. That is not a flaw; it means the material is alive.

The eight hexagonal screws and the octagonal bezel are not merely aesthetic — they impose a precise geometry that the strap must continue without visible interruption. With ceramic, the margin for error is zero; the material does not forgive rough approximations. That is why every piece that leaves my atelier is built for that specific watch, not an average size.
