Patek Philippe's shaped watches of the mid-twentieth century represent some of the manufacture's most adventurous design work, and few references capture this spirit quite like the ref. 1593. Introduced in 1944, the model remained in production for more than two decades, its distinctive silhouette earning it the affectionate nickname 'Hour Glass'. Unlike conventional rectangular dress watches, the 1593 features a subtly concave case that narrows through the centre before flaring dramatically towards its extremities. The result is a remarkably sculptural design, combining the elegance of a traditional dress watch with an architectural quality that feels surprisingly contemporary.

Dating to the 1950s, this example is particularly appealing for its 18K rose gold case, a less frequently encountered configuration than the yellow gold version. Measuring approximately 42mm by 25.5mm, its elongated proportions are complemented by a gently curved crystal and a restrained silvered dial with applied gold hour markers and subsidiary seconds at six o'clock. Inside is Patek Philippe's celebrated manually wound calibre 9-90, a rectangular movement developed specifically for shaped watches and used in some of the manufacture's most distinctive creations of the period. Produced in yellow, rose and white gold, as well as platinum, the ref. 1593 demonstrates how Patek Philippe could bring individuality to traditional watchmaking without sacrificing the elegance for which the company was renowned.

Watch is in overall excellent condition. The 18K rose gold case is well defined, with surface scratches and small marks. The case back shows some rubbing marks, while the hallmarks on the backs of the lugs remain fully legible. The Calatrava Cross-embossed winding crown is in excellent condition. The dial shows some surface marks and areas of degradation around the very outer edge. The applied hour markers show some tarnishing, while the hands remain clean. It is fitted with a leather strap and gold-coloured pin buckle.

Please Note: Due to CITES considerations, if the watch is to be shipped outside of the USA, the exotic skin strap will have to be removed.
