Your Patek Philippe watch is distinguished by its
self-winding 31-260 PS FUS 24H caliber combining
a Travel Time indication with an original 24-hour
display. It has two central hours hands: a solid one
for local time and a skeletonized one for home time.
To maintain an elegant case, Patek Philippe has
replaced the traditional local-time pushers on the
left side of the caseband with a patented correction
system using the crown pulled out to an intermediate
position (forwards and backwards correction in one-
hour increments). During these operations, the local
time hand is disengaged from the movement, thus
maintaining the accuracy of the minutes and seconds
hands. When not using the Travel Time function, the
two superimposed hours hands move in perfect syn-
chronization. The 24-hour display is distinguished
by its noon indication placed at 12 o’clock and not at
6 o’clock as is usually the case – thus ensuring excel-
lent legibility of all hours of the day. Equipped with
an off-centered platinum minirotor guaranteeing
excellent winding power, caliber 31-260 PS FUS 24H
– visible through a sapphire case back – also incor-
porates three patented innovations ensuring more
accurate information for the user.

INSTRUCTIONS
SECONDTIMEZONE
Your watch has two central hour hands:
- The solid hand displays local time (the time
zone in which you are currently located)
- The skeletonized hand
displays home time
(your normal place of residence or work)
When you are at home and therefore local time and
home time are the same, the hands are perfectly
aligned to appear as one.
When you change time zone, you can move the local
hour hand forwards or backwards one hour at
a time using the crown pulled out to position 2.
During this time, the skeletonized hand contin-
ues to indicate the time in your home time zone.
WINDINGCROWN
The winding crown is used to manually wind the
watch (position 1), to set the second time zone
(position 2) and to set the time (position 3).
WINDING
Your watch incorporates a self-winding movement.
The movements of your wrist set a centrifugal
weight 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 48 hours. When it has stopped after deplet-
ing the power reserve, it can be rewound by hand
(about 10 clockwise turns of the crown).

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
.
Your watch has two central hour hands
that move synchronously and can be either
superposed or separated in order to display
a second time zone.
The crown is used to move the local time
hand clockwise or counterclockwise in one-
hour steps.
If your watch has stopped running, rewind it
by hand before performing any corrections
or adjustments (about 10 clockwise turns of
the crown).
CAUTION
SETTINGTHETIME
– HOMETIME
The reference time for your watch is the time at
home. To set the time, first pull the crown out to
position 2. Then, move the local time hand (solid
hour hand) until the two hour hands (solid
and skeletonized ) are superposed. Now, pull the
crown gently all the way out to position 3 and move
the hour and minute hands in either direction until
the desired time is displayed. Once you have set the
correct time, push the crown home again. This will
set the small seconds hand in motion again (stop
second function).

DISPLAYOFASECOND
TIMEZONE – LOCALTIME
Before you set a second time zone , make sure that
the two superposed hour hands indicate the correct
time at home.
To set the local hour hand to display a second time
zone, follow these steps:
- If you are traveling eastbound, pull out the crown
to position 2. Then move the solid hand clock-
wise by as many hours as the two time zones are
apart (the local hour hand moves forwards by
one-hour steps).
- If you are traveling westbound, pull out the
crown to position 2. Then move the solid hand
counterclockwise by as many hours as the two
time zones are apart (the local hour hand moves
backwards by one-hour steps).
- If you continue your journey and pass through
further time zones, simply repeat the procedure
described above using the crown.
Note: When the two hour hands are separate, the skel-
etonized hand continues to display the time in your
home time zone.
As soon as you have returned to your home time
zone (normal place of residence or work), simply
superpose the two hour hands and again by
means of the crown. The local and home time are
then identical.

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.
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 its gain or loss remains
constant. Such a deviation can be easily corrected.
Consequently, the final test of accuracy takes place
on your wrist. Your temperament or the nature of
your physical activities can cause slight irregular-
ities. Fluctuations in position, temperature, or air
pressure, the presence of magnetic fields (as pro-
duced 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 such irregularities,

1716
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.
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.
