The Nautilus 7118/1A-001, seen from the bench

The Patek Philippe Nautilus ref. 7118/1A-001 is a 35.2mm stainless steel sports watch designed by Gérald Genta in 1976. It features the iconic porthole case and integrated bracelet characteristic of the Nautilus collection. This reference represents the feminine elegance of the line with pure architectural lines and refined functionality.

Frequently asked questions

Can a standard strap be fitted to the Patek Philippe Nautilus 7118/1A-001?

No. The bracelet is integrated into the case with a proprietary attachment: a standard strap has no way of connecting. This is not a limitation — it is the constructive nature of this watch. Anyone wishing to change the bracelet must go through the atelier, not a quick-release system.

How does the bespoke strap process work for this Nautilus?

I work by appointment only, through my <a href="/pages/casati-booking">Casati Milano</a> atelier. I bring the watch to the bench, take measurements directly from the case and build each attachment by hand. There are no ready-made templates for this model: every strap is made from scratch on that specific case.

Which leather do I recommend for this Nautilus?

I recommend naturally aged Barenia. The Nautilus 7118/1A is a sports watch with an elegant soul, and Barenia shares that same dual character: it starts composed, then opens up with wear and becomes something unrepeatable. It is the leather that ages the way a good relationship does.

How long does a well-made strap last?

With quality leather and ordinary care, I count on at least eight to ten years of regular use. Avoid prolonged exposure to water, let it breathe, and occasionally apply a little neutral cream. Leather does not deteriorate — it transforms. After a few years, a Barenia strap tells the story of the person who wore it.

The Nautilus was born in 1976 — what makes it still relevant today?

Gérald Genta drew an porthole case that looked like nothing else that existed at the time. The architectural geometry of the horizontal indices and a bracelet that becomes part of the case were radical ideas. I have watched decades of trends pass at the bench, and that form still holds because it was never a fashion: it was a structure.
