Patek Philippe Grand Complications 5204P-011

About This Watch

The Patek Philippe Grand Complications 5204P-011 is among the most complex wristwatches ever produced, combining a split-seconds chronograph with a perpetual calendar, representing the summit of Patek Philippe's watchmaking mastery. The caliber CHR 29-535 PS Q contains over 500 components that work in concert to deliver split-seconds timing accuracy, perpetual calendar functionality that correctly tracks days, dates, months, leap years, and moon phases until the year 2100. The black lacquered dial is organized with extraordinary clarity despite the wealth of information displayed: day and month at 12 o'clock, date and leap year indicator at 6 o'clock, moon phase and 30-minute counter within the sub-dials. The platinum case, identified by a small diamond set into the case side between the lower lugs (a Patek Philippe platinum hallmark), provides a dignified and substantial frame for this mechanical marvel. Each watch requires months of assembly and adjustment by a single watchmaker, and annual production is measured in single digits. The 5204P represents the kind of watchmaking achievement that only a handful of manufacturers in the world are capable of, and owning one places the collector in an extremely exclusive group of horological connoisseurs.
