WATER RESISTANCE
Although your watch is equipped with a water-
resistant crown, it is not protected against the
ingress of moisture because of the pushers for the
minute and date repeaters, the strikework mode
selector, and the alarm pusher.
Therefore, exercise care to ensure that liquid does
not come into contact with your watch.
SERVICE
We recommend that you have your watch
serviced at least once every five years. For this
purpose, we suggest you take it to an Authorized
Patek Philippe Retailer who will send it to our
Geneva manufacture. You can then be assured
that your watch will be inspected and overhauled
by a qualified master watchmaker at Patek Philippe
headquarters in Geneva. The master watchmaker
will completely disassemble the movement
and then inspect, clean, and lubricate all the
individual parts prior to reassembly. All functions
of the watch will also be tested in detail and the
escapement regulated if necessary. Finally, its
rate accuracy will be monitored and precision-
adjusted for a further period of at least two weeks.
The case and the buckle will be polished as per
your instructions and your watch will be returned
to you in mint condition. The entire process will
take several weeks because each watch must
undergo a complete series of tests to fulfill the
strict quality criteria of Patek Philippe.
If you have any questions regarding the
maintenance of your watch, contact the
Authorized Patek Philippe Retailer nearest you or
our International Customer Service department in
Geneva, or visit www.patek.com.
TIME SIDE
WINDING THE MOVEMENT
Your watch has a manually wound movement. It is
wound with the crown in position R (Remontage
= winding) as displayed by the crown position
indicator between 4 and 5 o’clock. Turn the crown
clockwise until the hand of the power-reserve
indicator at 9 o’clock (MOUVEMENT) reaches the
topmost position. When fully wound, the double
barrel has a power reserve of at least 72 hours.
Remove the watch from your wrist to wind it.
This way, you can avoid lateral pressure on the
winding stem which in the course of the years
could damage the stem tube. Use your fingernails
to pull out the crown and gently turn it between
two fingertips to set the time.
WINDING THE STRIKEWORK MECHANISM
Before you initiate a time strike, make sure the
small square window at 1:30 shows white. If it is
red, the strikework mechanism does not have
enough energy and is blocked. To wind its double
barrel, turn the crown counterclockwise. For
this purpose, the crown must be pushed home
(position R as displayed by the crown position
indicator between 4 and 5 o’clock). The strikework
mechanism is ready to operate when the small
round window shows white again. To enjoy
all of the functions of your watch, you should
wind the strikework double barrels until the
strikework power-reserve indicator at 3 o’clock
(SONNERIE) reaches the uppermost position.
When fully wound, the strikework mechanism
of the Grandmaster Chime has a power reserve of
30 hours in the
Grande Sonnerie
mode but this may
be reduced with the frequent use of the minute
and/or date repeaters.
