The master watchmaker will completely disas-
semble the movement and then inspect, clean,
and lubricate all the individual parts prior to reas-
sembly. 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 retur-
ned 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 mainte-
nance of your watch, contact the Authorized Pa-
tek Philippe Retailer nearest to you or our Inter-
national Customer Service department in Geneva,
or visit www.patek.com.
WINDING
When it is on your wrist, your watch is wound
automatically by your arm movements. When
fully wound and off the wrist, you watch has a
power reserve of at least 43 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.
CHANGING THE CASE BACK
Your watch comes with a sapphire-crystal case back
and a separate interchangeable solid metal back.
Only qualified master watchmakers at the Patek
Philippe workshops in Geneva are authorized to
exchange the backs.
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 ti-
mepiece.
