Strap for Nautilus 5711 White Gold / Grey

No. The Nautilus bracelet is integrated directly into the case: the attachment is proprietary and a standard buckle simply has nothing to grip. This is one of the reasons why this watch requires a completely different approach compared to an ordinary strap change. At the atelier I build the attachment to measure, working from the actual case.

Everything goes through <a href="/pages/casati-booking">Casati Milano</a>, by appointment only at Via XX Settembre 15, Milan. I bring the watch to the bench, take measurements directly from the white gold case and shape the attachment by hand to follow the original geometry. I do not work from templates or moulds: every strap is born on the client's watch.

For a watch with this character — sporting at heart, elegant in its materials — I choose aged Barenia. It develops a patina with wear that tells the passage of time without ever looking neglected. Against a white gold case, the warm contrast of Barenia works better than any surface-treated leather.

With quality leather and sensible daily use, ten years is a realistic expectation — and often you go beyond that. Care is straightforward: keep the leather away from prolonged water exposure and treat it every few months with a natural conditioner. Good leather does not deteriorate: it changes, softens and takes the shape of the wrist.

Gérald Genta designed it in 1976 with something specific in mind: a watch that worked equally well on a boat or at dinner. That dual character is in the Nautilus DNA. A leather strap does not betray the watch — it simply shifts the balance towards elegance, which on a white gold reference already takes precedence.
