Patek Philippe · Family: Grand Complications
The Patek Philippe Grand Complications Perpetual Calendar ref. 5327G-001 is a 39mm white gold dress watch with a perpetual calendar, part of the Grand Complications line the Geneva manufacture reserves for its most elaborate complications. It runs the ultra-thin automatic Caliber 240 Q, just 3.88mm thick. Cazador has no verified price observations yet for this reference. Its stand-out detail: the full perpetual calendar — day, date, month, leap year and moon phases — fits inside a 3.88mm-thick automatic movement thanks to its micro-rotor.

Caliber 240, introduced by Patek Philippe in 1977, was one of the manufacture's first ultra-thin automatic movements, achieved via a peripheral gold micro-rotor that spins within the movement's own plane rather than sitting atop it, keeping the whole assembly under 4mm thick. Since then, that caliber has served as the base for numerous complications across the brand's catalog, including the 240 Q perpetual-calendar version fitted to this reference.
The 5327G-001 belongs to the Grand Complications collection, the segment where Patek Philippe groups its most elaborately complicated watches — perpetual calendars, minute repeaters, tourbillons — apart from simpler executions in lines like Calatrava or Aquanaut. Its 39mm white gold case, with a Calatrava profile and scalloped flanks, houses a sunburst blue dial with applied white gold Breguet numerals and leaf-shaped hands.
Caliber 240 Q adds a full perpetual calendar function to the base movement: day, date, month and leap year are shown across windows and subdials, alongside an additional 24-hour indication and moon phases, all mechanically synchronized so no manual adjustment is needed until the year 2100, when the Gregorian calendar breaks its usual four-year leap cycle.
This is the thirteenth Patek Philippe reference Cazador adds, and the first from the Grand Complications family, extending the catalog alongside the Nautilus, Aquanaut, Calatrava, Complications, World Time, Golden Ellipse and Twenty~4 lines already present.

A complication that automatically displays the day, date, month and leap year without manual adjustment, even across months of different lengths, until the Gregorian calendar breaks its leap cycle in the year 2100.
Patek Philippe introduced it in 1977 as one of its first ultra-thin automatic movements, thanks to a peripheral gold micro-rotor. This reference's 240 Q version adds the perpetual calendar complication.
Between 38 and 48 hours, depending on the automatic micro-rotor's wind state, at a frequency of 21,600 vibrations per hour (3 Hz) with 27 jewels.
Grand Complications groups the manufacture's most elaborately complicated watches — perpetual calendars, minute repeaters, tourbillons — apart from simpler executions in lines like Calatrava, Nautilus or Aquanaut.
It reaches 30 meters of water resistance, a figure consistent with its role as a high-complication dress watch rather than a sports tool.
Day, date and month in windows, a leap-year indicator, a 24-hour subdial and the moon phase, all mechanically generated by Caliber 240 Q with no electronic modules involved.
