Frequently asked questions
Can a standard strap be fitted to the Royal Oak 26331IP.OO.1220IP.01?
No. The bracelet is integrated into the case: the attachment is proprietary and a standard spring bar has nothing to rest on. This is not a limitation — it is Genta's design signature. In the atelier I build the attachment by hand, directly on the watch case.
How does the bespoke strap service work for this Royal Oak?
I work by appointment only at <a href="/pages/casati-booking">Casati Milano</a>, at Via XX Settembre 15 in Milan. I bring the watch to the bench, take measurements directly from the case and craft every part of the attachment by hand. I do not work remotely: this watch requires a physical appointment.
Which leather do I recommend for this model?
For a Royal Oak in titanium and platinum I choose aged Barenia. Its compact structure handles the weight and geometry of the bracelet well, and over time it develops a patina that reflects genuine wear without giving way. I find it coherent with a watch that combines hard materials and refined form.
How long does a well-made strap last?
With quality leather and basic care — keeping it dry, avoiding unnecessary folding, conditioning it once a year — I comfortably reach ten years of use. Barenia, in particular, improves with time: it softens, takes shape around the wrist, gains character. A strap that ages poorly is almost always a strap that was made in a hurry.
What makes the titanium-platinum combination of this Royal Oak special?
Titanium and platinum have very different densities: the result is a watch that sits lightly on the wrist yet has an intense visual presence — almost contradictory. I have seen very few watches capable of feeling both robust and light at the same time. For anyone building a bespoke strap, that duality is the starting point — every choice of leather and finish must speak to that contrast.
