The Nautilus 7018/1A-011, seen from the bench

The Patek Philippe Nautilus 7018/1A-011 is a women's sports watch featuring a 33.6 mm stainless steel case with integrated bracelet, designed by Gérald Genta in 1976. This iconic model combines the distinctive porthole-shaped case with integrated bracelet in a single steel sculpture. The watch requires custom strap solutions tailored to its integrated attachment points for seamless integration with the original case.

Frequently asked questions

Can a standard strap be fitted to the Patek Philippe Nautilus 7018/1A-011?

No. The bracelet is integrated into the case: there is no standard lug to attach an off-the-shelf strap. The attachment is part of the case structure itself. That is why I only work bespoke, with the watch physically in front of me at the atelier.

How does the bespoke strap service work for this Nautilus?

Everything goes through <a href="/pages/casati-booking">Casati Milano</a>, by appointment at Via XX Settembre 15 in Milan. I bring the watch to the bench, study the exact geometry of the attachments, and build the strap directly on the case. I do not work from photographs or measurements sent by email: the precision required here leaves no room for approximation.

Which leather do I recommend for this model?

For a Nautilus like this one — born sporty but often worn in elegant settings — I prefer a matte alligator in a neutral tone, smoke grey or slate blue. It holds the technical character of the case without undermining the refinement of the Patek signature. I have seen too many poor pairings on this watch: polished leather tends to compete with the steel, while matte accompanies it.

How long does a well-made strap last?

With regular use and some care, five years is a starting point, not a finish line. Quality leather ages with the watch: it changes colour, settles on the wrist, tells the time that has passed. The one real rule is to keep it away from prolonged contact with water and let it breathe and dry naturally after perspiration.

The Nautilus was born in 1976 — what does that mean for someone wearing it today?

Gérald Genta reportedly drew this watch in a single night. True or not, the design has remained intact for nearly fifty years — and this 33.6 mm variant carries that character forward in a more compact proportion. I have seen Nautilus pieces from the Seventies still wearing perfectly: that is the measure of a design built to last, not to impress at first glance.

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.
