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 with the 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 examples with polychrome cloisonné enamel dials.
Around 1 000 examples were produced; some with integrated bracelet.
The watch is so-called “Hour Glass” by collectors.
The lady version bears the Ref. 2261 (made between 1948 and the mid-1950’s).
