Frequently asked questions

Can a standard strap be fitted to the Royal Oak Offshore 26280ST.OO.D022CU.01?

No. The bracelet is integrated into the case: the attachment is proprietary and a standard strap simply cannot connect physically. This is a design choice, not a limitation. At the atelier, I build every strap directly on the watch, bespoke, with no compromises.

How does the bespoke strap service work for this model?

I work by appointment only, at <a href="/pages/casati-booking">Casati Milano</a>, Via XX Settembre 15, Milan. The watch comes to the bench, I take measurements directly from the case and hand-shape the attachments so the strap dialogues with the original octagonal architecture. There is no template: every piece is built from scratch on that specific watch.

Which leather do I recommend for the Royal Oak Offshore given its sporting character?

I choose Mississippi Alligator: it has a clean scale pattern, serious long-term durability and holds its own against the muscular character of this watch without looking out of place. As an alternative, multi-year vegetable-tanned Tuscan leather ages honestly and gains character with daily wear. I avoid overly delicate leathers — they are simply not suited to a watch built to be worn hard.

How long does a well-made artisan strap last?

With quality leather and sound construction, I expect at least five to seven years of regular use. Care is straightforward: keep it away from prolonged water exposure and occasionally condition the leather with a neutral product. Alligator and Barenia age by developing a patina that tells the story of time worn — they do not deteriorate, they transform.

The Royal Oak Offshore was born as a provocation — what does that mean in practice for those who wear it today?

In 1993 this watch was called the 'Beast', because it pushed Genta's integrated design language past every acceptable boundary. Whoever wears it today inherits that choice: this is a watch that takes up space on the wrist and does not ask permission. I often see it paired poorly, with anonymous straps that contradict its character. A bespoke strap, built with the same technical care as the case itself, restores coherence to the whole.

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.
