Made to Measure

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.

FAQ

Can a strap be fitted to the Patek Philippe Nautilus 7118/1300R-001?

The Nautilus lug system is an integral part of the case design — not a conventional lug, but a sculptural extension of the case horns. A bespoke strap, built by taking measurements directly from the watch, is the proper solution, and that is precisely the work carried out by <a href="/pages/casati-booking">Casati Milano</a>.

How does the bespoke strap-making process work for this model?

During the atelier appointment, the craftsman takes physical measurements directly from the case: the geometry of the horns, the caseback height, and the transition curve. The strap is then built from scratch based on these dimensions, with the client choosing the leather, colour, stitching and clasp. No pre-made templates are used — every piece is unique.

Which leather best suits the character of the Nautilus 7118/1300R-001 in rose gold?

The rose gold of the 7118 pairs naturally with natural calf in cognac or honey, which enhances its warm tonality. For a more formal register, smooth calf in midnight blue or slate grey echoes the opaline dial. Those seeking texture may consider Mississippi alligator in neutral tones, without overpowering the refinement of the case.

How long does a bespoke artisan strap last?

A strap made from selected leathers, reinforced stitching and correct construction will last for years with minimal care: avoid prolonged exposure to water and fragrances, and store the watch on a proper rest when not worn. The patina that develops over time on quality leather is part of the piece's value, not a flaw.

What is the movement of the Patek Philippe Nautilus 7118/1300R-001 and what defines it?

The calibre 324 S C is an in-house Patek Philippe movement displaying hours, minutes, central seconds and date. Finished to Geneva Seal standards, it features a Gyromax balance wheel with a gold hairspring. Its architecture reflects the manufacture's philosophy: no superfluous complications, uncompromising construction quality.
