Frequently asked questions

Can a strap be fitted to the Audemars Piguet Royal Oak 26347TI.OO.D004CR.02?

Not in the conventional sense. The bracelet is integrated into the case: there is no standard lug where an off-the-shelf strap can be attached. The only way to change it is to build a bespoke attachment, shaped directly around the geometry of your specific piece. That is what I do in the atelier, one watch at a time.

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

I work by appointment only, through <a href="/pages/casati-booking">Casati Milano</a>, my atelier at Via XX Settembre 15 in Milan. You bring the watch: I take measurements directly from the case, study the curve of the attachment, and build the strap around that specific geometry. No templates. Every piece starts from scratch on the physical watch.

Which leather do I recommend for this model?

For a Royal Oak in titanium with a flyback chronograph, my choice is hand-treated Tuscan leather with a brushed finish to echo the case. Titanium has a technical, understated character: a leather that is too formal or too polished creates a contrast that simply does not work. Tuscan leather ages with the wrist, adapts, and keeps a sporting read without tipping into casual.

How long does a well-made strap last?

With quality leather and solid construction, I count on five to eight years of regular use. It depends greatly on how you care for it: I always keep a second strap for summer, because perspiration wears leather faster than time does. With the right conditioning, the leather does not deteriorate — it transforms, takes on the shape of the wrist, and often looks better than the day I delivered it.

What does having a flyback chronograph on this Royal Oak mean in practice?

The flyback lets you reset and restart the chronograph in a single action, without stopping and restarting in two separate steps. It is a function born in aviation, where every second matters. On this Royal Oak the mechanics match the character of the case: nothing superfluous, everything in service of legibility. I have seen many complicated chronographs over the years — a well-calibrated flyback is one of those complications you genuinely appreciate in use, not just under glass.

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.
