The Patek Philippe Grand Complications reference 5204G-001 is a high-end timepiece featuring a 40mm case crafted from 18k white gold with a thickness of 14.3mm. It is characterized by its sunburst olive green dial with a black-gradient rim, adorned with white gold applied baton-style faceted hour markers and luminescent coating. The watch is paired with a shiny olive green calfskin leather strap and a white gold fold-over clasp. It is powered by the manually wound caliber CHR 29-535 PS Q, a movement known for its traditional architecture and seven patented innovations, providing a power reserve of approximately 65 hours and a frequency of 28,800 vibrations per hour.
This model houses a highly complex array of complications, most notably a split-seconds (rattrapante) chronograph and a perpetual calendar. The dial displays the day and month in apertures below 12 o’clock, while the date is indicated by a hand at 6 o’clock, which also contains the moon phase display. Additional indicators include small seconds at 9 o’clock, an instantaneous 30-minute chronograph counter at 3 o’clock, a leap year indicator between 4 and 5 o’clock, and a day/night indicator between 7 and 8 o’clock. The split-seconds function, operated via a pusher integrated into the crown, allows for the timing of two concurrent events.
General reviews of the 5204G-001 often emphasize its modern and athletic aesthetic compared to previous rose gold or platinum iterations. Critics and enthusiasts highlight the exceptional hand-finishing of the movement and the refined complexity of the “stepped” lug case design. While its 14.3mm height is noted as substantial for a dress-oriented watch, the overall wearability is frequently praised, particularly with the inclusion of both sapphire crystal and solid white gold interchangeable casebacks. The desaturated green dial is often described as subtle and sophisticated, though some collectors note that the high retail price and extreme technical density position it as a niche piece for serious horological enthusiasts.
