Patek Philippe Geneve Mode D'emploi page 7

The master watchmaker will completely
disassemble the movement and then inspect,
clean, and lubricate all 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 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 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, contact the
Authorized Patek Philippe Retailer nearest you or
our International Customer Service department in
Geneva, or visit www.patek.com.
WINDING
Your watch is wound automatically by the
movements of your wrist, which set a winding
mechanism in motion. When fully wound and off
the wrist, you watch has a power reserve of at least
38 hours. If it was set aside for a longer period of
time and is no longer running, it can be manually
wound with about then 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.
WATCH WINDER
Your self-winding wristwatch was presented to you
in a case with a winder. Keep your watch in this
winder if you do not intend to wear it for several
days. The constant motion of the winder will
keep your watch wound and no time or calendar
adjustments will be needed when you put it on
again.
PATEK PHILIPPE SEAL
As a comprehensive seal 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 visible appearance of the timepiece. Its
applicability to the technical, functional, and aesthetic
aspects of the watch takes into consideration not
only the artisanship with which it was crafted, but
also covers its rate accuracy, its dependability, and
the quality of customer service. Moreover, it stands
for the entire know-how and all the special skills
invested in the development, production, and long-
term maintenance of an extraordinary timepiece.
CHANGING THE CASE BACK
Your watch comes with a sapphire-crystal case
back as well as with an interchangeable solid-metal
back. Only qualified master watchmakers at the
Patek Philippe workshops in Geneva are authorized
to exchange the backs.
