Patek Philippe, Ref. 1593:
This reference is launched in 1944 and remained in production until the late-1960’s. This rectangular-shaped watch is fitted withthe Cal. 9-90. The majority in yellow gold, more rarely in rose gold and even more rarely in platinum. This reference was also made in very few exampleswith polychrome cloisonné enamel dials. Around 1 000 examples were produced; some with integrated bracelet. The watch is so-called “Hour Glass” bycollectors. The lady version bears the Ref. 2261 (made between 1948 and the mid-1950’s).
