The Patek Philippe ref. 2523 was launched in 1953 and featured the legendary Louis Cottier World Time movement. What makes these watches particularly sought-after by collectors is the center dial featuring a cloisonne enamel map of a part of the world. Versions were also made without an enamel center dial and we are just as eager to buy one of these versions as we have a home for any variation of a ref. 2523.
