In 1941, Patek Philippe began the regular pro-
duction of chronographs with perpetual calendars.
Since then, these timepieces have been amongst
the most widely sought-after Grand Complication
wristwatches of all time. Your watch is endowed
with the caliber CH 29-535 PS Q: the first perpet-
ual calendar chronograph movement to be entirely
developed and manufactured in-house at Patek
Philippe’s own workshops. It is distinguished by its
traditional architecture (column wheel, horizontal
clutch, and manual winding), combined with six
patented innovations. The addition of a perpetual
calendar required the development of a new calen-
dar mechanism defined by an exceptionally slim
design (1.65 mm for 182 parts). The movement’s
architecture and refined finishes can be admired
through a sapphire crystal case back. The dial is
reminiscent of classic Patek Philippe perpetual cal-
endar chronographs: the day and month in a double
aperture at 12 o’clock, and a pointer-type date dis-
play at 6 o’clock with an integrated moon-display
aperture. The watch is distinguished by several
unique features, including two small, round aper-
tures for the day/night and leap-year indication, as
well as subsidiary seconds and a 30-minute counter
positioned slightly below the central axis. Despite
its eleven displays, the dial offers exceptional clar-
ity and readability.
