The line of perpetual calendar chronograph wristwatches is one of the cornerstones of Patek Philippe’s collection. It all began in 1940 with the introduction of reference 1518; since then, the line has continuously been in production until now, spawning five main references. It is however only in recent times, with the introduction of reference 5004 in 1996 that a split-second feature was added to the ensemble. Then, in 2012 reference 5204 made its debut, featuring the same set of complications but with a fully in-house movement, while reference 5004 was powered by a Lemania-based calibre.

The addition of a split-second feature propels the watch into the ultimate echelon of watchmaking, the split-second chronograph being one of the most daunting complications to execute, together with the minute repeater. Such mechanical prowess coupled with the generous proportions of the watch and the quintessentially Patek Philippe design of the piece made reference 5204 an instant classic, highly coveted by collectors. Unfortunately, the intricacy of the movement requiring highly skilled watchmakers to assemble them, means that only an extremely scarce number of watches are produced each year, making the model one of the hardest to source.

The present example of this coveted model is offered in practically “as-new” condition and complete of its sale accessories.
