The Royal Oak 15202BC.OO.1240BC.01, seen from the bench

The Royal Oak represents Audemars Piguet's flagship model, characterized by the octagonal case with integrated bezel and visible screws. The reference 15202BC.OO.1240BC.01 mounts the automatic AP 2121 caliber with hour, minute and date indication. The ultra-thin movement ensures a contained profile while maintaining the essential functions.

Frequently asked questions

Can a standard strap be fitted to the Royal Oak 15202BC.OO.1240BC.01?

No. The bracelet is integrated directly into the case: there is no standard lug to attach a conventional strap. The attachment is part of the octagonal architecture itself. Every intervention must therefore be built from scratch, on that specific watch.

How does the bespoke strap service work for this Royal Oak?

I work exclusively through <a href="/pages/casati-booking">Casati Milano</a>, by appointment only, in the atelier. I take measurements directly from the case at the workbench — no templates exist for this model. Every attachment is hand-shaped to follow the original octagonal geometry without any forcing.

Which leather do I recommend for this Royal Oak in white gold?

I recommend Mississippi Alligator. Its natural texture speaks to the exposed hexagonal screws without overpowering them, and the leather develops a patina cleanly over time. White gold has a cool elegance: alligator in tobacco or midnight blue tones balances it without adding visual weight.

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

A strap built with first-choice leathers easily lasts eight to ten years with regular wear. The key is care: no direct water contact, a light application of neutral cream twice a year. Good leather does not deteriorate — it transforms, gaining character and becoming more personal over time.

What sets the Royal Oak 15202BC apart from other Royal Oak references?

It is the Ultra Thin reference, born directly from the spirit of Gérald Genta's original 1972 design. Seven millimetres of white gold case: a measurement that demands absolute constructive discipline. I have seen many Royal Oaks at the workbench over the years, but this one has a slimness that changes how it sits on the wrist — you barely feel it, yet it is unmistakably present.
