The caliber CH 29-535 PS movement
trolled by a column wheel, considered to be the
defining hallmark of traditional chronographs. As
always at Patek Philippe, it is crowned with a pol-
ished cap. The watch has a chronograph hand, a
seconds subdial, and an instantaneously jumping
minute counter. Its large four-spoke Gyromax
balance wheel with four poising weights beats
at a frequency of 4 Hz (28,800 semi-oscillations/
hour). The caliber has a guaranteed power reserve
of 65 hours (50 hours when the chronograph is
activated). The clutch lever exhibits the classic "S"
shape. The design of the two characteristic bridges
in these types of watches – the chronograph-wheel
bridge and the minute-counter bridge – demon-
strates a sublime sense of aesthetics. The move-
ment also has a stop-seconds feature that makes it
very convenient to accurately set the time when
the crown is pulled.

configuration of the bridges is to minimize friction
