Patek PhilippeThis Patek Philippe wristwatch, reference 5204P-001, is a complex timepiece featuring a split-seconds chronograph and a perpetual calendar. Encased in platinum, the watch measures 40 mm in diameter and 14 mm in thickness.
The silver dial is distinguished by applied luminous oxidized gold baton indexes and matching oxidized gold luminous baton hands. It displays multiple functions, including a 30-minute register, leap year, day/night indicator, moon phases, and date. The timepiece is powered by the manual-wind caliber CHR 29-535 PS Q, which is rhodium-plated and features fausses cotes decoration and 34 jewels. The movement is fitted with a Gyromax balance and a free-sprung Breguet balance spring.
This example includes a platinum deployant clasp, an additional solid caseback, a setting pin, a wooden box, and a Certificate of Origin. It represents an early generation of the reference, introduced following the discontinuation of the reference 5004.

- Case and Dial Design
- The watch is constructed with a three-body platinum case featuring a polished finish and a concave bezel. It is fitted with fluted lugs and a transparent screw-down case back, providing a view of the movement. The case band incorporates four correctors to manage the perpetual calendar functions, and the crown contains a co-axial pushbutton specifically for the split-seconds chronograph mechanism. The silver dial employs a layout with applied luminous oxidized gold baton indexes. The hands are oxidized gold with a luminous finish. Sub-dials and apertures are integrated to display the 30-minute register, leap year, day/night cycle, month, day of the week, moon phases, and the date. An outer 1/5th seconds track is marked with 5-second Arabic numerals.
- Movement Specifications
- The movement is the Patek Philippe caliber CHR 29-535 PS Q, a manually wound mechanism. It is rhodium-plated and finished with fausses cotes decoration. The caliber includes 34 jewels and utilizes a straight-line lever escapement. Regulation is achieved through a Gyromax balance and a self-compensating, free-sprung Breguet balance spring. The movement bears the Seal of Geneva quality mark. This movement serves as a development for the brand, housing both the chronograph functions and the perpetual calendar module within the same caliber. It was engineered to replace the movement used in the predecessor reference 5004.
- Provenance and Identification
- The watch is identified as the first generation of the reference 5204P-001, a variant produced circa 2013. It was originally launched at the 2012 Basel Watch Fair. This specific configuration is distinguished from later iterations, such as the 5204P-010 and 5204P-011, by its specific dial markers and hands. The watch is offered as a complete set, including its original fitted wooden box, the Certificate of Origin, a solid platinum caseback, and a setting pin.
