cate 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 un-
dergo a complete series of tests to fulfill the strict
quality criteria of Patek Philippe.
If you have any questions regarding the main-
tenance of your watch, contact the Authorized
Patek Philippe Retailer nearest you or our Inter-
national Customer Service department in Geneva,
or visit www.patek.com.
WINDING
Your watch is wound automatically by the move-
ments of your wrist, which set a winding mecha-
nism 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 ten 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 Ref. 5074 is delivered with a winder. Keep
your watch in this box if you intend not to wear
it for a longer period of time. The rotation of the
watch holder will keep it wound and you will not
have to reset the time when you put your watch
on again.
Within 24 hours, the winder will move your watch
during 8 hours and let it rest for 16 hours.
PATEK PHILIPPE SEAL
As a comprehensive seal of quality, the Patek Phi-
lippe 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 aesthe-
tic 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-me-
tal back. Only qualified master watchmakers at the
Patek Philippe workshops in Geneva are authorized
to exchange the backs.
