PERPETUAL CALENDAR

Crafted entirely in the manufacture’s Grand
Complication workshops and featuring the prestig-
ious Patek Philippe Seal, the self-winding caliber
240 Q movement is composed of 275 parts yet stands
apart with its ultra-thin 3.88-mm profile. This is
possible because of an off-center mini-rotor in 22K
gold and the ingenious arrangement of the perpet-
ual calendar and moon-phase mechanisms. With
its 48-month (four-year) cam, the perpetual calendar
automatically displays the correct date, taking into
account months with 31, 30 and 28 days, as well
as February 29 in leap years. It does not have to
be corrected until 2100 – a secular year when the
Gregorian calendar will omit February 29. All cal-
endar indications can easily be corrected via four
push pieces recessed in the side of the case.

INSTRUCTIONS
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. 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.
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.
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 self-winding movement.
The movements of your wrist set a centrifugal mass
in motion; this tensions the mainspring, which stores
the energy. When you take off your fully wound
watch, it will continue to run for at least 38 hours.
When it has stopped after depleting the power
reserve, it can be rewound by hand (about 10 clock-
wise turns of the crown).
Your complicated self-winding wristwatch was pre-
sented to you in a case with a winder. If you do not
intend to wear your watch for a longer period of
time, please return it to the case where the constant
motion of the winder will keep it wound. By using
the winder, you can eliminate the need to reset the
calendar when you put on your watch again.

1110
Please wind the watch and set the time before
you 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.
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 4 p.m. and 1 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
PREPARATIONS
1. If your watch has stopped running, rewind it by
hand before performing any corrections or adjust-
ments (about 10 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. as follows:
advance the hands until the 24-hour hand points
at 6 o’clock (in the subsidiary dial at 9 o’clock).
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.

1312
MOONPHASE
CORRECTION
Each time the correction push piece at 6 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 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 num-
ber of days that have elapsed since the last full moon.
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 = 1
st
year after leap year; 2 = 2
nd
year after leap year;
3 = 3
rd
year after leap year). Visit www.patek.com to
find the current leap-year cycle.
DAYOFWEEKCORRECTION
To set the day of the week , actuate the correction
push piece at 9 o’clock as many times as needed
to display the current day.

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.
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 self-
winding 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

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.
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.
