A HIGHLY
SOPHISTICATED MOVEMENT
Crafted entirely in the manufacture’s Grand
Complication workshops and featuring the pres-
tigious 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 minirotor
in 22K gold and the ingenious arrangement of the
perpetual calendar and moon-phase mechanisms.
With its 48-month (four years) cam, the perpetual
calendar automatically displays the correct date,
taking into account months with 31 and 30 days,
as well as February 29 leap years. It does not have
to be corrected until 2100, a secular year when the
Gregorian calendar will omit the 29th of February.
All calendar indications can easily be corrected via
four push pieces recessed in the side of the case.

12 INSTRUCTIONS
winding crown
The winding crown is used to wind the watch
(position 1) and to set the time (position 2). If
your watch is equipped with a screw-down crown
(Nautilus model), unscrew the crown completely
before winding.
winding
Your watch incorporates a self-winding move-
ment. The movements of your wrist set a centrifu-
gal mass in motion; this tensions the mainspring
which stores the energy. When you take off your
fully wound watch, it will continue to run at least
38 hours. When it has stopped after depleting the
power reserve, it can be rewound by hand (about
10 clockwise turns of the crown). Please wind the
watch before you put it on. This way, you can avoid
lateral pressure on the winding stem which in the
course of the years could damage the stem tube.
Your complicated self-winding wristwatch was
presented 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.
notes on correcting calendar displays
– Use only the correction stylus delivered with
your watch to press the push pieces. Any other
tool could damage the case.

13
– Do not perform any calendar corrections
between 3 p.m. and 2 a.m. During this period, the
mechanisms that change the displays are active
and could be damaged by manual interventions.
– All settings and corrections must be performed
in the specified order.
1. preparations
Start by manually winding the movement (max.
10 turns of the crown) to get it going before
proceeding with any other setting or correction.
Advance the hands with the crown until the
24-hour hand (in the subsidiary dial at 9 o’clock)
points at 6 o’clock.
2. setting/correcting the date
Repeatedly press the push piece between 11 and
12 o’clock or at 11 o’clock (Nautilus model) until
the correct date is displayed on the subsidiary
dial at 6 o’clock.
3. setting/correcting the leap year cycle
and the month
Repeatedly press the push piece between 12 and
1 o’clock or at 1 o’clock (Nautilus model) until
the subsidiary dial at 3 o’clock displays the cor-
rect year (4 represents the leap year) and the
correct month. Leap year cycles can be found in
the “Full moon and leap year calendar” brochure
delivered with your watch.

14 4. setting/correcting the day of the week
If the day-of-week display at 9 o’clock does not
correspond with the date, repeatedly press the
push piece at 9 o’clock until the correct day
appears on the subsidiary dial at 9 o’clock.
5. setting/correcting the moon phase
Each time you press the push piece at 6 o’clock
or at 5 o’clock (Nautilus model), the moon-
phase display will advance by one day.
Advance the lunar disk until the full moon
appears in 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 push
piece as many times as days have elapsed since
the last full moon.
6. setting the time
Gently pull the crown out to position 2, and
move the hands to set the correct time. If you
move the hands forward beyond midnight, all
calendar displays will advance by one day. Press
the crown home again.
If your watch is equipped with a screw-down
crown (Nautilus model), unscrew the crown
completely before you set the time. Then pull
the crown out to position 2 and proceed with
the setting. Finally, push the crown all the way
in and screw it tight again.

15
Caution: Please 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 environment or under-
water: the water resistance of your watch is assured only
when the crown is pushed home.

TAKING CARE
OF YOUR WATCH
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 com-
pleted with your name. It guarantees the authen-
ticity 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 jour-
nals. 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 techni-
cal, functional, and aesthetic factors, but also rate
accuracy, dependability, and customer service
quality. Additionally, it reflects the maker’s know-
how and all other assets needed for the develop-
ment, production, and long-term maintenance of
an extraordinary timekeeping instrument.

18 quality control
The movements and completely assembled watches
are subject to a series of technical tests and visual
inspections to verify their rate accuracy, power
reserve, reliability, water resistance, and overall
appearance. After it was assembled, your self-wind-
ing watch will already have run for several weeks
before leaving the workshops; it fully complies with
the stringent criteria of the Patek Philippe Seal.
rate accuracy
The rate accuracy of Patek Philippe watches is veri-
fied 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
–
3and +2 seconds per 24 hours.
The precision of a watch is determined by how
accurately 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. The last test of
accuracy takes place on your wrist. Your tempera-
ment or the nature of your physical activities can
cause slight irregularities. Fluctuations in posi-
tion, temperature, or air pressure, the presence of
magnetic fields (as produced by most electronic
devices, metal detectors, household appliances,
etc.) as well as vibrations and other factors may
also affect its accuracy.
Should you notice that your watch exhibits 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.

19
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 caseback
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.
service
We recommend that you have your watch ser-
viced every three to five years. For this purpose,
we suggest that you bring or send your watch to an
Authorized Patek Philippe Retailer or an Authorized
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 one of the Authorized Service Centers.
The watchmaker will completely disassemble the
movement and then clean and inspect all parts
and lubricate them in the reassembly process. 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.

20 If you have any questions regarding the maintenance of your
watch or need the address of the Authorized Patek Philippe
Service Center nearest you, contact our International Customer
Service department in Geneva, or visit www.patek.com.
