Frequently asked questions

Can a standard strap be fitted to the Royal Oak Offshore 26540ST.OO.A070CA.01?

No. The bracelet is integrated directly into the case: there are no standard lugs to attach an aftermarket strap. It is a deliberate design choice, not a limitation. In the atelier I build the attachment from scratch, shaped by hand around the physical watch.

How does the bespoke strap service work for this model?

I work exclusively through <a href="/pages/casati-booking">Casati Milano</a>, by appointment only, at Via XX Settembre 15 in Milan. I take the watch to the bench, measure directly from the case, and build every component of the attachment around the actual geometry of that specific piece. I do not work remotely, and I do not work from photographs.

Which leather do I recommend for this Royal Oak Offshore?

I recommend matte Mississippi alligator. The Offshore has a muscular, direct character — a glossy or overly refined leather creates a contrast that feels wrong. Matte alligator holds the sporting tone of the case without compromising on material quality. It ages well and wears without fuss.

How long does a well-made strap last on a watch like this?

A strap built from first-quality leather, properly maintained, easily lasts five or six years of daily use. Leather should not be feared: clean it, let it dry naturally after perspiration, and condition it occasionally with a neutral product. Over time it develops a patina that reflects how it has been worn — and to me, that is the mark of an honest material.

Was the Offshore genuinely born as a provocation to the original Royal Oak?

Yes, and you can still feel it today. In 1993 Le Brassus presented a watch designed for those who found the original Royal Oak too restrained. The exposed screws, the octagonal bezel taken to extreme proportions, the total integration of case and bracelet — every choice says something precise about the character of the person wearing it. It was never meant to be a neutral watch.

The next step

The right strap isn't chosen. It is built, together.
