Care and maintenance
SErvIcE
We recommend that you have your watch serviced
at least once every three to five years. For this
purpose, we suggest you take it to an Authorized
Patek Philippe Retailer who will send it to our
Geneva manufacture, the only location authorized
to service watches with minute repeaters. You can
then be assured that your watch will be inspected
and overhauled by a qualified master watchmaker
at Patek Philippe headquarters in Geneva.
The master watchmaker will completely disassem-
ble the movement and then inspect, clean, and lu-
bricate 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 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 depart-
ment in Geneva, or visit www.patek.com.
cHANGING THE cASE bAck
Your watch comes with a sapphire-crystal case
back and a separate solid precious metal back.
Only qualified master watchmakers at the Patek
Philippe workshops in Geneva are authorized to
exchange the backs.

The Patek Philippe Seal is a global emblem of qual-
ity 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 cov-
ers 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 en-
titled. It encompasses the entire know-how and
the unique facets that govern the development,
production, and long-term maintenance of an
exceptional timepiece.
