Your Patek Philippe Reference 5235 wristwatch
features an unusual face that clearly sets it apart
from conventional timepieces. Its regulator dial
has three separate display zones for hours, min-
utes, and seconds. The configuration combines a
subsidiary hours dial at 12 o’clock, a sweep minute
hand, and a subsidiary seconds dial at 6 o’clock; this
face was inspired by the large and highly accurate
freestanding regulator clocks once used by watch-
makers, scientific institutions, and major seaports
to keep a precise track of the time. To prevent the
hour hand from partially covering the seconds dial
twice a day for several hours, it was simply moved
aside to the periphery of the dial. The oscillator of
your Annual Calendar Regulator is nothing short of
avant-garde, featuring a Spiromax
®
balance spring
and a Pulsomax
®
escapement (the spring, lever, and
escape wheel are made of Silinvar
®
, a silicon-based
material) as innovative and patented components.
Additionally, your watch is endowed with an Annual
Calendar that only needs to be corrected once a year.

INSTRUCTIONS

Your watch has a stop-seconds mechanism that halts
the second 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 second hand will start running again.
ANNUALCALENDAR
The Annual Calendar indicates the day of the week,
the month, and the date, automatically taking into
account months with 30 and 31 days. If the watch
is worn daily, the date only needs to be corrected
on March 1 (forward by 3 days in non-leap years,
and by 2 days in leap years). A calendar correction
may also be necessary if the watch was set aside for
a longer period of time and stopped running. If the
hands are moved clockwise beyond midnight, the
calendar displays will advance by one day.
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).
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.

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 fol-
lows: advance the hands beyond midnight (the date
will change, unless it was 12 noon) and then keep
advancing the hands to 6 a.m.
3. Make sure to set the date to the first day of the
month with the correction push piece between
9 and 10 o’clock.
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 corrections
between 8 p.m. and 3 a.m.
The calendar corrections must be per-
formed 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
4. Correct the date
5. Correct the day of the week
6. Set the time

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.
DATECORRECTION
To set the date , actuate the correction push piece
between 9 and 10 o’clock as many times as needed
to display the current date.
MONTHCORRECTION
To set the month , actuate the correction push piece
at 10 o’clock as many times as needed to display
the current month.
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.

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.
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.
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

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

Votre montre-bracelet Patek Philippe Référence
5235 présente un visage très inhabituel, avec un
cadran
de type «régulateur» affichant séparément
les heures, les minutes et les secondes. Cette dis-
position inédite – petite aiguille des heures à 12h,
grande aiguille centrale des minutes, petite aiguille
des secondes à 6h – s’inspire des horloges de préci-
sion appelées «régulateurs» qui servaient autrefois
à indiquer le temps exact dans les manufactures hor-
logères, les institutions scientifiques et les grands
ports. Pour éviter que l’aiguille des heures ne masque
deux fois par jour pendant un long moment l’affi-
chage des secondes, l’indication des heures a été
déplacée à la périphérie du cadran. Au cœur de votre
garde-temps se trouve un organe régulateur révolu-
tionnaire, avec des composants novateurs brevetés
– spiral Spiromax®et échappement Pulsomax®(spi-
ral, ancre et roue d’ancre fabriqués en Silinvar®, un
dérivé breveté du silicium). Votre montre est équi-
pée par ailleurs d’un Quantième Annuel n’exigeant
qu’une seule correction par an.
