The Heritage
The strap for this watch is made to measure
On the Patek Philippe Twenty~4 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 Twenty~4 4911G-001?
The case attachment on the Twenty~4 4911G-001 is an integral part of the case design: there are no conventional interchangeable lugs, and a standard straight-bar strap cannot be fitted to the geometry of this piece. The solution is a bespoke strap, built directly on the watch by <a href="/pages/casati-booking">Casati Milano</a> following a precise survey of the case dimensions. It is not an adaptation — it is a project conceived around the watch itself.
How does the bespoke strap-making process work for this model?
The craftsman at Casati Milano receives the watch in the atelier and records the geometry at the case ends: curvature, thickness, and the profile of the transition between case and bracelet. A custom attachment is then constructed on these measurements, after which the client selects the leather, colour, and buckle. All work is carried out by hand, with edge finishing and final assembly calibrated to the specific watch.
Which leather best suits the character of the Patek Philippe Twenty~4 4911G-001?
The chromatic temperature of white gold calls for leathers in neutral or cool tones: pearl-grey smooth calfskin, matte-finished alligator belly, or ostrich in dove-grey tones are the most coherent choices. Matte alligator in particular balances the brilliance of the metal by absorbing rather than reflecting light, preserving the understatement that defines this model. A white gold or satin-silver buckle completes the visual register without interruption.
How long does a well-made bespoke strap last?
A strap built with first-quality leather, hand-finished edges, and precisely calibrated stitching can last many years with ordinary care: avoid prolonged contact with water, apply a leather conditioner periodically, and store it away from direct heat sources. The patina that develops over time on certain leathers — calfskin, box calf — is part of the piece's value, not a sign of wear. A well-maintained strap ages alongside the watch.
When was the Patek Philippe Twenty~4 created, and what distinguishes it within the manufacture's output?
The Twenty~4 was created in 1999 as Patek Philippe's response to the demand for a ladies' watch that could be worn daily without compromising the manufacture's Genevan identity. What sets it apart is the coherence of its design: case and bracelet are conceived as a single volume, not as separately assembled components. The in-house calibre E15 delivers hours and minutes with the precision and reliability that characterise every piece leaving the Rue du Rhône.
