Made to Measure

The strap for this watch is made to measure

On the Audemars Piguet CODE 11.59 the bracelet is drawn as part of the case: no catalogue strap will fit. In the atelier we take the measurements on the watch itself and build the strap on the piece — that is the work of Casati Milano.

FAQ

Can a standard strap be fitted to the Audemars Piguet CODE 11.59 26397OR.OO.D417CR.01?

No. The bracelet is integrated into the case with a proprietary attachment: no off-the-shelf strap fits without intervention. This is not a shortcoming — it is the construction logic of this watch. At the atelier, I build every strap directly on the case, made to measure.

How does the bespoke strap service work for this model?

I work exclusively by appointment at <a href="/pages/casati-booking">Casati Milano</a>, at Via XX Settembre 15 in Milan. Bring the watch with you: I take measurements from the actual case, not from technical sheets. Every lug is shaped by hand to respect the architecture of the case. The result is a strap made for that specific watch.

Which leather do I recommend for this CODE 11.59 in pink gold?

I favour Mississippi Alligator in cognac or warm tobacco tones. Pink gold has a chromatic depth that pairs naturally with amber-toned leathers — not to match, but to converse. The alligator grain adds visual structure without overshadowing the complexity of the case.

How long does a well-made artisan strap last?

With ordinary care, five years is a reasonable minimum — often considerably more. I avoid direct water contact and store the watch off the strap when not wearing it. Quality leather does not deteriorate: it ages, gains character, tells the story of time worn. That is something I have learnt over years at the bench.

Why does the CODE 11.59 require 140 hours of hand-finishing?

The case has five different finishing planes, with alternating convex and concave surfaces. Every transition between planes must be executed and checked by hand — a machine cannot distinguish those details. I have seen up close what it means to work on this geometry: the complexity is not decorative, it is structural. That is precisely why the strap must be built with the same level of care.

The next step

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

From the atelier appointment to delivery, every step is made for those who know that things done well take time. Rare leathers, one piece at a time, eighteen months of warranty.
