The Nautilus 5711/1A-011, seen from the bench

The Nautilus was introduced in 1976 with Gérald Genta's design characterized by an octagonal case with integrated lugs. The reference 5711/1A-011 features the automatic caliber 324 S C with functions of hours, minutes, seconds, and date. 40mm stainless steel case with screw-down crown and pushers.

Frequently asked questions

Can a standard strap be fitted to the Patek Philippe Nautilus 5711/1A-011?

No. The bracelet is integrated directly into the case: there are no standard lugs to attach a traditional strap. The attachment is proprietary, conceived by Gérald Genta as an inseparable part of the overall form. For anyone wanting a leather strap, the only option is to have one built to measure, on the watch itself, in the atelier.

How does the bespoke service at Casati Milano work for this model?

<a href="/pages/casati-booking">Casati Milano</a> works by appointment only, at Via XX Settembre 15 in Milan. I ask the client to bring the watch: I take measurements directly from the case, study the morphology of the original attachments and shape each lug by hand. There is no pre-made template for the Nautilus — every strap is built from scratch on that specific piece.

Which leather do I recommend for the Nautilus?

I prefer aged Barenia. Its character suits a watch that is sporting yet carefully finished: it starts firm, almost stiff, then softens and takes on the mark of the person wearing it. It is understated at first, beautiful after years of use. For those wanting something more structured and visible, Mississippi Alligator is my second choice — but it needs to be used with restraint.

How long does a well-made leather strap last?

With a first-selection leather and solid construction, I reckon at least five to seven years of regular use. Care is straightforward: keep it away from prolonged exposure to water and condition the leather every few months with a neutral product. Barenia in particular ages in a visible and pleasing way — it becomes more personal over time, it does not deteriorate.

Why has the Nautilus retained this weight in the market for nearly fifty years?

I have seen many sports watches in steel pass through the bench. The Nautilus holds because Genta drew a shape that does not depend on fashion: that porthole case with the lateral ears works equally well with a jacket or an open shirt. It is not a question of hype — it is architecture that worked in 1976 and still works today. That sets it apart from almost everything else.
