Movement technical data
wINDING
When fully wound, your wristwatch has a power
reserve of at least 38 hours. We recommend that
you wind your watch at about the same time every
day.
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 ye-
ars, 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 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 quality
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 ser-
vice 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.
