Frequently asked questions
Can a standard strap be fitted to the Royal Oak 15510ST.OO.1320ST.01?
No, and the reason is structural. The bracelet is integrated into the case: there is no traditional lug where a ready-made strap can be attached. The only viable option is to build a bespoke attachment directly on the watch, in the atelier.
How does the bespoke strap service work for this Royal Oak?
I work exclusively by appointment at <a href="/pages/casati-booking">Casati Milano</a>, at Via XX Settembre 15 in Milan. I bring the watch to the bench, study the geometry of the octagonal case and hand-shape every millimetre of the attachment, respecting the original proportions. There are no templates: each piece is built from scratch on that specific watch.
Which leather do I recommend for the stainless steel Royal Oak?
For a watch with this character — sporting at heart, but built with architectural rigour — I prefer natural Barenia. It ages with dignity, developing a patina that works beautifully alongside the satin and polished steel of the Royal Oak. Mississippi alligator is a strong alternative for those who want a bolder contrast between leather and case.
How long does a well-made strap last?
With quality leather and minimal care, I count on five to eight years of regular use. Keep it away from prolonged water exposure and let it breathe after a demanding day. Barenia in particular does not deteriorate: it transforms, and over time it becomes more beautiful than the day I delivered it.
What is the character of the Royal Oak compared to other sports watches in steel?
In 1972, Gérald Genta did something nobody had dared before: he took steel — a material considered secondary — and treated it with the same care usually reserved for gold. The octagonal case with exposed screws is not decoration, it is structure. I have seen many sports watches at the bench over the years, but few have this consistency between form and intention.
