TIME SIDE
Selecting a second time zone
The dial of the Grandmaster Chime has three
hands from the center: two gold hands for the
local time in hours and minutes, and a short
gold hand with a ring-shaped tip for the hours
in a second time zone. With the two pushers
at 8 and 10 o’clock, this second time zone can
be selected bidirectionally in one-hour steps
without affecting the progression of the other
hands and time displays.
With the “+” pusher, the hand is moved forward
hour by hour to select a time zone to the east
of the current location or, with the “-” pusher,
backward hour by hour to select a time zone to
the west. The second time zone is coupled with
a day/night indicator in a small round window
(blue or white) so it is easy see whether it is
daytime or nighttime there.
Setting the moon phase
The moon phase display is set with the correction
push piece in the case flank between 4 and 5
o’clock next to the inscription LUNE. Each time it
is actuated, the moon phase will advance by one
day. Press it as often as needed to display a full
moon. Consult a moon-phase calendar or log on
to our website www.patek.com to find out how
many days have elapsed since the last full moon
(including the day on which you correct the
display). To set the moon-phase display, actuate
the correction push piece as often as days have
elapsed since the last full moon.
