Launched in 2012, the reference 5204 featured the manufacturer’s first in-house split-seconds perpetual chronograph, caliber CHR 29-535 PS Q, replacing the former Lemania-based caliber CHR 27-70Q. The watch was updated with a 40mm diameter case, featuring a day and night indication in place of the 24-hour indicator, baton numerals replacing the former applied gold Arabic numerals and a slight tweak in the layout of the dial with a noticeable “upside down” moon-phase display resembling a “smile.” The reference was released first in platinum with an opaline silver dial and, two years later, a black dial version was launched, with pink gold variants subsequently released. The addition of a split-second chronograph complication 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 the reference 5204 an instant classic, highly coveted by collectors.

Consigned by the original owner, the present watch is accompanied by its Certificate of Origin, presentation box, additional hard case back, hang tag, and setting pin. The watch is preserved in outstanding overall condition and was probably only worn a handful of times. The reference 5204 is a milestone timepiece, featuring Patek Philippe’s innovative in-house movement and representing a new beginning in Patek Philippe’s long, traditional history.
