and lubricate all the individual parts prior to re-
assembly. All functions of the watch will also be
tested in detail and the escapement regulated if
necessary. Finally, its rate accuracy will be moni-
tored and precision-adjusted for a further period
of at least two weeks.
The case and the buckle will be polished as per
your instructions and your watch will be returned
to you in mint condition. The entire process will
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, contact the Authorized Patek Philippe Retailer
nearest you or our International Customer Service depart-
ment in Geneva, or visit www.patek.com.
wINDING
When it is on your wrist, your watch is wound auto-
matically by your arm movements. When fully wound
and off the wrist, you watch has a power reserve of at
least 38 hours. If your watch stopped because you set
it aside for an extended period of time, you can wind
it manually with about 20 turns of the crown.
We advise you to 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.
The same applies to handsetting. Please use your
fingernails to pull the crown out and turn it gently
between two fingertips.
BOX wITH wATCH wINDER
Your reference is delivered in a box with a built-
in winder. Keep your watch in this box if you
do not intend to wear it for a longer period of
time. Thanks to the built-in winder, the watch
will remain wound and the hands do not need to
be set when you decide to wear it again.
PATEK PHILIPPE SEAL
The Patek Philippe Seal is a global emblem of qua-
lity that applies to the completed and fully cased
watch. It covers the movement, the case, the dial,
the hands, the pushers, the straps and bracelets,
the clasps, as well as all other components that
contribute to the accuracy and aesthetic appeal of
a watch. It takes technical, functional, and design-
related aspects into account and also covers the
visual appearance of the watch, its rate accuracy
and dependability, as well as the quality of the
customer service to which its owner is entitled. It
encompasses the entire know-how and the unique
facets that govern the development, production,
and long-term maintenance of an exceptional
timepiece.
