Frequently asked questions
Can a standard strap be fitted to the Royal Oak 77451OR.ZZ.1361OR.01?
No. The bracelet on this Royal Oak is integrated directly into the case, with a proprietary attachment that no standard strap can replicate. There are no reliable adapters that respect the original octagonal geometry. The only proper solution is to build a strap to measure, starting from the actual case.
How does the bespoke strap service work for this Royal Oak?
I work on this model exclusively through <a href="/pages/casati-booking">Casati Milano</a>, by appointment at the atelier, at Via XX Settembre 15 in Milan. I bring the watch to the bench, take measurements directly from the case, and build each lug terminal by hand, millimetre by millimetre, to achieve a seamless integration with the original octagonal bezel. I do not work from photographs or measurements provided by the client: the watch must be present.
Which leather do I recommend for this Royal Oak in pink gold?
I recommend hand-finished Mississippi alligator in warm tones — amber honey or light tobacco — because it works naturally with the warmth of pink gold without overpowering it. This 34mm Royal Oak has an elegant character built on precise proportions: a fine-grained leather with a natural sheen respects that architecture without overshadowing it. I avoid saturated colours or heavy patinated finishes: what this watch calls for is balance, not contrast.
How long does a well-made artisan strap last?
A strap built with quality leather and solid stitching will easily last five to seven years with regular wear. The key is care: keep it away from water, apply a little neutral cream each season, and rotate between two straps if the watch is worn frequently. Leather ages — and on a well-tanned alligator, ageing is a quality, not a flaw: the patina that forms over the years tells a story, it does not hide one.
Why are the eight hexagonal screws on the Royal Oak such an important detail?
Gérald Genta designed them in 1972 as a visible structural element, not as decoration. They are the architectural signature of the watch: they secure the octagonal bezel to the case and define the entire proportion of the dial. When I build a strap for this model, I always start from that geometry — the terminal must meet the angles of the bezel without interrupting them. If the strap ignores that logic, the watch loses its visual coherence.
