setting
correcting the moon phase
Each time you press the push piece at 2 o'clock,
the lunar disk will advance by half a day. To set the
moon phase, begin by advancing the lunar disk until
it displays a full moon. Then consult a calendar or
www.patek.com (click on Collection Movements–
Complications Moonphase indicator) to determine
how many days have elapsed since the last full
moon (including the day on which the correction
is being made). To set the moon-phase display to
the proper position, press the moon-phase correc-
tion push piece twice for each day since the last full
moon (not counting the day of the last full moon).
Caution:
To actuate the moon-phase correction push piece,
always use the stylus that is delivered with your watch. The
use of any other tool could damage your timepiece.
