Perpetual Calendar Reference 5204/1R, a rose gold manual wind wristwatch with split-seconds chronograph, Circa 2019

Launched in 2012, the reference 5204 is the successor of the reference 5004, both exhibiting a perpetual calendar and split seconds chronograph. Comparing these two references together, one can easily recognize the inspiration of reference 5004 on reference 5204, but with the latter displaying a handful of upgrades while conveying its own merits.

Made exclusively in either platinum or pink gold, the reference 5204 has enjoyed different dial variations after its debut in 2012, with the present watch offered with a black dial and rose gold case. The dial displays the calendar work for the perpetual calendar, the chronograph registers, the subsidiary seconds and an inverted moon phase, with all features balanced out, rendering a beautiful symmetry. The 5204 houses the calibre CH 29-535 PS Q and tops it off with a spring-loaded split seconds lever, reducing offset between the chronograph and split seconds hands, furthermore improving its surgical precision. Registered for an astounding amount of six patents in its painstaking movements, reference 5204 is a true testimony of Patek Philippe’s groundbreaking innovations.
