Strap for Golden Ellipse 5738 Rose Gold / Black

Not a standard one: the attachment is an integral part of the case design and does not feature conventional spring-bar lugs. A strap can indeed be made, but it must be built to measure directly on the watch by <a href="/pages/casati-booking">Casati Milano</a>. The process begins with a precise measurement of the actual case profile, ensuring a seamless transition between the elliptical case and the strap.

The watch is brought in person to the atelier, where craftsmen take direct measurements from the original piece, recording the exact geometry of the case-to-strap junction. Thickness, curvature and profile are faithfully reproduced in the finished strap. The choice of leather, colour, finish and clasp is discussed with the client during the appointment, making each piece entirely unique.

The 5N rose gold of the case pairs naturally with warm, mature leathers: Mississippi alligator in cognac or tobacco, navy box calf for a tonal accord with the dial, or dark brown Nile crocodile with a natural patina. Leathers with a refined yet understated texture work best, complementing the delicacy of the elliptical profile without overwhelming it. A rose gold clasp completes the material continuity of the piece.

A strap crafted from first-cut leather, hand-sewn and properly reinforced can comfortably last ten years or more with standard care. Longevity depends on the quality of the leather, the precision of the case fit and daily usage. Casati Milano uses only carefully selected materials and traditional tailoring techniques that ensure lasting durability without sacrificing suppleness.

The Calibre 240 is one of the thinnest automatic movements ever produced by Patek Philippe, featuring a 22-carat gold micro-rotor positioned at the periphery to minimise overall thickness. This technical choice is inseparable from the aesthetic: it is the very condition that allows the Golden Ellipse's slim, flat profile to maintain its golden ratio proportions. Hours and minutes only — functional purity that mirrors the formal purity of the ellipse.
