The Nautilus 7118/1200R-001, seen from the bench

The Nautilus 7118/1200R is a 35.2mm rose gold sports watch designed by Gérald Genta in 1976. This model features an integrated case and bracelet with a distinctive porthole-style design. The complex geometry of the integrated lugs requires custom strap solutions for optimal fit and aesthetics.

Frequently asked questions

Can a standard strap be fitted to the Patek Philippe Nautilus 7118/1200R-001?

No. The bracelet is integrated directly into the case: there are no traditional lugs to attach a standard strap. The attachment geometry is entirely proprietary. If you want to wear this watch on leather, the only option is to have a strap built to measure, starting from the actual case.

How does the bespoke strap service work for this Nautilus?

I only work on these attachments at <a href="/pages/casati-booking">Casati Milano</a>, by appointment. I bring the watch to the bench, take measurements directly from the case, and shape every element by hand. There are no templates: each strap is made for that specific piece.

Which leather do I recommend for the Nautilus in rose gold?

On this watch I prefer Mississippi Alligator in warm tobacco or aged cognac tones. The warmth of rose gold pairs naturally with those shades. Natural Barenia is a solid alternative: it ages with the wrist and, over time, tells its own story.

How long does a well-made artisan strap last?

With regular wear and a little care, five years is a starting point. Quality leather does not deteriorate: it transforms. I keep the strap away from prolonged moisture and let it rest occasionally. A good Alligator, properly tanned, improves with time rather than worsening.

What makes the Nautilus design distinctive compared to other sports watches?

In 1976 Gérald Genta did something that seemed unusual at the time: he took the shape of a ship's porthole and built a sports watch in precious metal around it. The case integrated with the bracelet is not purely aesthetic — it is a structural idea. On this 35.2mm rose gold reference, that tension between hard form and refined proportions is still very much alive.

The next step

The right strap isn't chosen. It is built, together.
