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 on the Patek Philippe Twenty~4 7300/1200A-001?
The bracelet attachment is an integral part of the case design: the lugs flow from the middle case in a single architectural line that does not accommodate a standard spring-bar attachment. A bespoke strap, built directly on the watch, is the solution — and that is precisely the work carried out by <a href="/pages/casati-booking">Casati Milano</a>, a sartorial atelier in Milan working by appointment.
How does the bespoke strap-making process work for this model?
The process begins in the atelier with a direct measurement of the watch's actual proportions: lug curvature, effective width, and the transition angle between case and bracelet. A dedicated last is then constructed from those measurements, and the strap is hand-stitched in the leather chosen by the client using a double-thread saddle stitch. The result is a unique piece, calibrated to that specific watch.
Which leather best suits the character of the Patek Philippe Twenty~4 7300/1200A-001?
A smooth calf with a satin finish complements the brushed steel texture of the bracelet, maintaining visual coherence across surfaces. Alligator — Belly or Hornback cut — introduces an organic grain that catches light differently from the set diamonds, creating a refined material dialogue. The choice depends on context: everyday urban wear or more formal occasions.
How long does a well-made bespoke strap last?
A strap built with top-grade tannery leathers and hand-sewn with a double saddle stitch typically lasts between five and ten years with regular wear, developing a personal patina that deepens its character over time. Longevity also depends on care: avoiding prolonged exposure to moisture and applying an appropriate leather conditioner occasionally will significantly extend the strap's life.
What makes the calibre 324 S C in the Twenty~4 significant compared to other movements in its category?
Calibre 324 S C is a manufacture movement produced entirely by Patek Philippe, featuring a Gyromax balance wheel and a Spiromax balance spring in Silinvar — materials that offer superior thermal stability and magnetic resistance compared to traditional components. It combines hours, minutes, centre seconds and an instantaneous date within a movement sized for a 36mm case, without compromising power reserve. It is not a base ébauche reworked; it was conceived from the outset for this watch.
