A HIGHLY
SOPHISTICATED MOVEMENT
Crafted entirely in the manufacture's Grand
Complication workshops
and featuring the pres-
tigious Patek Philippe Seal, the self-winding caliber
240 Q movement is composed of 275 parts yet
stands apart with its ultra-thin 3.88-mm profile.
This is possible because of an off-center minirotor
in 22K gold and the ingenious arrangement of the
perpetual calendar and moon-phase mechanisms.
With its 48-month (four years) cam, the perpetual
calendar automatically displays the correct date,
taking into account months with 31 and 30 days,
as well as February 29 leap years. It does not have
to be corrected until 2100, a secular year when the
Gregorian calendar will omit the 29th of February.
All calendar indications can easily be corrected via
four push pieces recessed in the side of the case.
