In 1941, Patek Philippe began the regular pro-
duction of chronographs with perpetual calendars.
Since then, these timepieces have been amongst
the most widely sought-after Grand Complication
wristwatches of all time. Your watch is endowed
with the caliber CH 29-535 PS Q: the first perpet-
ual calendar chronograph movement to be entirely
developed and manufactured in-house at Patek
Philippe’s own workshops. It is distinguished by its
traditional architecture (column wheel, horizontal
clutch, and manual winding), combined with six
patented innovations. The addition of a perpetual
calendar required the development of a new calen-
dar mechanism defined by an exceptionally slim
design (1.65 mm for 182 parts). The movement’s
architecture and refined finishes can be admired
through a sapphire crystal case back. The dial is
reminiscent of classic Patek Philippe perpetual cal-
endar chronographs: the day and month in a double
aperture at 12 o’clock, and a pointer-type date dis-
play at 6 o’clock with an integrated moon-display
aperture. The watch is distinguished by several
unique features, including two small, round aper-
tures for the day/night and leap-year indication, as
well as subsidiary seconds and a 30-minute counter
positioned slightly below the central axis. Despite
its eleven displays, the dial offers exceptional clar-
ity and readability.

INSTRUCTIONS
WINDINGCROWN
The winding crown is used to manually wind the
watch (position 1) and to set the time (position 2).
WINDING
Your watch incorporates a manually wound move-
ment. Fully wound and with the chronograph dis-
engaged, it will continue to run for at least 55 hours.
We recommend that you wind your watch at about
the same time every day, preferably in the morning.
We recommend that you wind your watch at about
the same time every day, preferably in the morning.
Turn the crown clockwise gently and steadily, and
stop when you feel resistance. Excessively forceful
winding could damage the movement.

9
SETTINGTHETIME
To set the time, gently pull the crown all the way
out and move the hands in either direction. Once
you have set the correct time, push the crown home
again. The day/night indicator allows you to verify
whether the time displayed by your watch is between
6 a.m. and 6 p.m. (white) or between 6 p.m. and 6 a.m.
(blue). When you turn the hands clockwise beyond
midnight, the calendar displays will advance as
well. We advise against turning the hands coun-
terclockwise across midnight because this would
desynchronize the calendar displays; however, it
would not damage the calendar mechanism.
Your watch has a stop-seconds mechanism that halts
the seconds hand as soon as you pull the crown out
to position 2. This allows you to synchronize your
watch with an acoustic time signal to one-second
accuracy. As soon as you push the crown home (posi-
tion 1), the seconds hand will start running again.

10
CHRONOGRAPH
The chronograph is started and stopped with the
pusher at 2 o’clock. The chronograph and minute -
counter hands are reset to zero with the pusher
at 4 o’clock.
TACHYMETER
Your watch has a tachymeter scale calibrated to
1000 meters . On a highway, a car passenger
would typically start the chronograph when pass-
ing a kilometer sign and stop it when passing the
next one. The chronograph hand shows the elapsed
time between the signs and, on the tachymeter
scale, the average speed of the car during the meas-
urement. It therefore measures the time needed to
travel a given distance rather than the distance
travelled within a given time.

11
PERPETUALCALENDAR
The perpetual calendar indicates the day of the week,
the date, and the month, automatically taking
into
account months with 28, 29, 30, and 31 days. It
switches directly from September 30 to October 1
or from February 28 to March 1. In leap years, it
also displays February 29 and then jumps directly
to March 1 at midnight. In addition to the date,
day, and month, the watch also features a leap-year
display. The moon-phase display is highly accurate:
it deviates from the true lunar cycle by merely one
day every 122 years. If the watch is wound daily,
the perpetual calendar will not require any man-
ual corrections before February 28, 2100; this is a
secular year that by exception omits February 29.

12
Please wind the watch and set the time before
y
ou put the watch on. This prevents lateral
pressure on the winding stem. Please use
your fingernails to pull the crown out and
turn it gently between two fingertips.
Never pull out the crown in a humid envi-
ronment or underwater: the water resist-
ance of your watch is assured only when
the crown is pushed home.
We recommend that you wind your watch
fully at about the same time every day, pref-
erably in the morning.
Correction push pieces should be actuated
exclusively with the correction stylus that
was delivered with the watch. The use of any
other tool could damage your timepiece.
Do not perform any calendar or moon-phase
corrections between 5.30 p.m. and 2 a.m.
The calendar corrections must be performed
strictly in the order described below:
1. Move the hands to 6 a.m.
2. Set the date to the first day of the month
3. Correct the month and the leap-year
cycle
4. Correct the date
5. Correct the day of the week
6. Correct the moon phase
7. Set the time
CAUTION

13
PREPARATIONS
1. If your watch has stopped running, rewind it
fully before performing any corrections or adjust-
ments (50 clockwise turns of the crown).
2. You can be sure that performing adjustments is
safe if you first set your watch to 6 a.m.; observe
the color of the day/night indicator (white).
3. Make sure to set the date to the first day of the
month with the correction push piece between
11 and 12 o’clock.
DATECORRECTION
To set the date , actuate the correction push piece
between 11 and 12 o’clock as many times as needed
to display the current date.

14
MONTHANDLEAPYEAR
CYCLECORRECTION
To simultaneously set these two displays and ,
actuate the correction push piece between 12 and
1 o’clock as many times as needed to display the
current month and the current year (4 = leap year;
1 = 1st year after leap year; 2 = 2nd year after leap
year; 3 = 3rd year after leap year)
. The “Full moon
and leap year calendar”
brochure delivered with
your watch will show you the current leap year cycle.
DAYOFWEEKCORRECTION
To set the day of the week , actuate the correction
push piece between 10 and 11 o’clock as many
times as needed to display the current day.

15
MOONPHASE
CORRECTION
Each time the correction push piece between
6 and 7 o’clock is actuated, the moon-phase disk
will advance by one day. To begin the correction
procedure, advance the moon-phase disk until a full
moon is displayed in the middle of the aperture.
Consult the “Full moon and leap year calendar”
brochure, an almanac, or visit www.patek.com and
count the number of days that have elapsed since
the last full moon (relative to the current date). To
set the correct moon phase, press the correction
push piece as many times as the number of days
that have elapsed since the last full moon.

MAINTENANCE
CERTIFICATEOFORIGIN
Your watch is delivered with a certificate of origin
that indicates the movement and case numbers. The
certificate is valid only if it is dated, signed by an
Authorized Patek Philippe Retailer, and completed
with your name. It guarantees the authenticity of
your watch and validates your warranty privileges
for a period of two years after the date of sale. The
unique movement and case numbers of each watch
are transcribed into the workshop journals. With
this information, you may have yourself entered
in the Patek Philippe Register of Owners and will
obtain the International Patek Philippe Magazine free
of charge.
PATEKPHILIPPESEAL
As an all-encompassing hallmark of quality,
the Patek Philippe Seal applies to the entire
watch, including the movement, case, dial,
hands, pushers, strap, and clasp as well as to all other
facets that contribute to the precision and aesthetic
perfection of the timepiece. It covers the technical,
functional, and aesthetic factors, but also rate accu-
racy, dependability, and customer service quality.
Additionally, it reflects the maker’s know-how and
all other assets needed for the development, produc-
tion, and long-term maintenance of an extraordinary
timekeeping instrument.

17
QUALITYCONTROL
The movements and completely assembled watches
are subject to a series of technical tests and visual
inspections to verify their rate accuracy, winding
speed, power reserve, reliability, water resistance,
and overall appearance. Once assembled, your man-
ually wound watch will run for several weeks before
leaving the workshops; it fully complies with the
stringent criteria of the Patek Philippe Seal.
ACCURACY
The rate accuracy of Patek Philippe watches is ver-
ified in several phases of manufacturing, both with
uncased and fully cased movements. The final test
is performed with a wrist motion simulator and
the results must conform to the following Patek
Philippe precision benchmarks:
The rate accuracy of calibers with a diameter of 20 mm
or larger must range within -3 and +2 seconds per
24 hours.
The precision of a watch is determined by how accu-
rately it keeps the time. A watch that is fast or slow
is considered precise if the amount by which it is
fast or slow remains constant. Such a deviation can
be easily corrected. Consequently, the final test of
accuracy takes place on your wrist. Your tempera-
ment or the nature of your physical activities can
cause slight irregularities. Fluctuations in position,
temperature, or air pressure, the presence of mag-
netic fields (as produced by most electronic devices,
metal detectors, household appliances, etc.) as well
as vibrations and other factors may also affect its
accuracy. If you notice that your watch exhibits

18
such irregularities, please do not hesitate to take
it to an Authorized Patek Philippe Retailer or an
Authorized Service Center where no effort will be
spared to assure that it is adjusted to meet your
expectations.
WATERRESISTANCE
Your watch is fitted with different types of seals
to protect the movement against the ingress of
dust and moisture and to prevent damage if it is
immersed in water. Nonetheless, we recommend
that you prevent direct contact with water if your
watch has a leather strap.
It is advisable to have a water-resistance test car-
ried out every year on your watch. This is a simple
procedure that takes only a few minutes at a prop-
erly equipped point of sale.
CHANGINGTHECASE
BACK
If your watch was delivered with two interchangea-
ble case backs, please note that only an Authorized
Patek Philippe Retailer or an Authorized Service
Center is qualified to exchange the case backs.

19
SERVICE
We recommend that you have your watch serviced
every three to five years. With this in mind, we
suggest that you take or send your watch to an
Authorized Patek Philippe Retailer or an Author-
ized Service Center. This gives you the assurance
that your watch will be entrusted to the hands of
a qualified Patek Philippe watchmaker in Geneva
or at an Authorized Service Center.
The watchmaker will completely disassemble the
movement and then inspect, clean, and lubricate
all of 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 two weeks. The
entire process may 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 or need the address of your closest
Authorized Patek Philippe Service Center, contact our
International Customer Service Department in Geneva,
or visit www.patek.com.
