SETTING AND CORRECTING THE PERPETUAL CALENDAR
The individual calendar displays are adjusted with
the correction push pieces in the case flank. They
are identified with engraved inscriptions.
SETTING THE DATE (SUBSIDIARY DIAL AT 6 O’CLOCK)
The date is set with the correction push piece
labeled QUANTIEME. Each time it is actuated,
the date hand in the subdial at 6 o’clock (on both
sides of the watch) will advance by one day.
SETTING THE DAY (SUBSIDIARY DIAL AT 9 O’CLOCK)
The day of the week is set with the correction
push piece labeled JOUR. Each time it is actuated,
the day hand in the subdial at 9 o’clock will
advance by one day.
SETTING THE MONTH (SUBSIDIARY DIAL AT 3 O’CLOCK)
The month is set with the correction push piece
labeled MOIS. Each time it is actuated, the month
hand in the subdial at 3 o’clock will advance by
one month.

SETTING THE YEAR (IN THE CENTER OF THE DIAL) AND
THE LEAP YEAR CYCLE (SUBSIDIARY DIAL AT 6 O’CLOCK)
The Grandmaster Chime features a four-digit year
display and a leap-year cycle dial with quadrants
numbered 1 to 4; the 4 identifies a leap year.
Because the leap-year cycle is correlated with
the year, these two displays are mechanically
interconnected. Contrary to the other calendar
displays, they do not advance instantaneously.
They switch slowly in the course of a few hours
ahead of the year change. Thanks to Patek
Philippe’s convenient solution, they can be
corrected forward or backward. This is done with
the two correction push pieces marked “+” and
“-” next to the inscription MILLESIME. Each time
one of these correction push pieces is actuated,
the year display will switch forward or backward
by one year and the leap-year display by one
quadrant.
