The Heritage
The strap for this watch is made to measure
On the Patek Philippe Nautilus the bracelet is drawn as part of the case: no catalogue strap will fit. In the atelier we take the measurements on the watch itself and build the strap on the piece — that is the work of Casati Milano.

Can a strap be fitted to the Patek Philippe Nautilus 7018/1A-010?
The Nautilus attachment is an integral part of the case design: a standard straight-lug strap is not compatible with the proprietary lug geometry of this model. A strap is entirely achievable, built to measure directly on the watch by <a href="/pages/casati-booking">Casati Milano</a>, starting from a precise survey of the actual timepiece. It is a bespoke process that respects — and enhances — Gérald Genta's original architecture.
How does the bespoke strap-making process work for this model?
The process begins with an appointment at the atelier, where the master leatherworker takes direct measurements from the client's watch: lug geometry, case thickness, and curvature. The strap is then built from these actual measurements, with the client choosing leather, colour, stitching, and buckle together with the craftsman. No component is pre-made: every detail is tailored to that specific Nautilus.
Which leather best suits the character of the Patek Philippe Nautilus 7018/1A-010?
The 34mm Nautilus pairs naturally with leathers offering a refined texture and quality finishing: belly or hornback alligator echoes the satin-and-polished duality of the steel case, while navy box-calf dialogues with the model's characteristic dials. Fine-grain ostrich is a contemporary choice that complements rather than competes with the octagonal case geometry. The final selection is made in the atelier, comparing the leather directly against the physical watch.
How long does a well-made bespoke strap last?
A strap built with first-selection leather and hand stitching can last many years when properly maintained: it should be protected from prolonged moisture, allowed to breathe after wear, and periodically treated with products suited to the specific leather. Construction quality is equally important — double-layer build, hand-burnished edges, and waxed thread are hallmarks of lasting craftsmanship. A well-made strap develops a personal patina over time, adding character rather than showing wear.
What is the history of the movement fitted in the Nautilus 7018/1A-010?
The calibre 324 S C is a Patek Philippe manufacture movement offering hours, minutes, centre seconds, and a date disc. It is an automatic calibre built to the standards of the Geneva Seal: hand-finished components, a Gyromax balance regulated in six positions, and extremely tight production tolerances. Its presence in a 34mm Nautilus confirms that Patek Philippe has never differentiated between 'men's' and 'women's' calibres: manufacture quality is identical across the range.
