Strap for Twenty-4 Perpetual Calendar Rose Gold / Green

The Twenty~4's attachment is an integral part of the case design, with proprietary terminals whose geometry does not accommodate an off-the-shelf strap without compromising the formal coherence of the piece. A strap is entirely possible — it simply needs to be made to measure, built directly on the watch by <a href="/pages/casati-booking">Casati Milano</a>. The master leather craftsman takes the actual dimensions of the terminals and constructs the strap to match the specific geometry of this model.

The client brings the watch to the atelier during a scheduled appointment: the craftsman takes a direct reading of the terminal dimensions — width, lug curvature, case profile — and works with the client to select leather, colour, stitching and closure type. Production is entirely by hand, with each layer of leather shaped around the real geometry of the Twenty~4. The result is a seamless transition between metal and leather, conceived specifically for this watch.

Smooth calf in natural tones — sand, greige, nude — preserves the architectural linearity of the rose gold case without competing with the warmth of the metal. Mississippi alligator in hornback cut introduces a rhythm of symmetrical scales that complements the rectangular geometry of the dial. For those seeking chromatic contrast, a grain calf in bordeaux or plum enhances the depth of the rose gold through opposition.

A strap built with first-grade leather, saddlery stitching and hand-finished edges has a structural lifespan measured in years of daily use, not seasons. Longevity depends on the type of leather, the owner's care and exposure to moisture and perspiration: leathers such as alligator and vegetable-tanned calf develop a personal patina over time that enriches their character. The atelier can assess maintenance work or stitching renewal when required.

Calibre 240 Q is an automatic movement with a 22-carat gold micro-rotor: its ultra-thin architecture was designed not to compromise the rectangular case profile, maintaining contained thickness despite the complexity of the integrated perpetual calendar. The automatic management of date, day, month, leap year and moon phases — requiring no manual correction for over a century — within a 36 mm rose gold case represents one of the most accomplished syntheses of feminine aesthetics and in-house watchmaking engineering.
