Care And Maintenance; Water Resistance - Patek Philippe Reference 5950 Mode D'emploi

Care and Maintenance

WATER RESISTANCE

Your watch is fitted with different types of seals
to protect the movement against the ingress of
dust and moisture and to prevent damage if it
is immersed in water. However, if your watch
receives a blow to the crown or the crystal, its
water resistance may be impaired.
If your watch has a leather or satin strap, we
recommend that avoid exposing it to water alto-
gether.
SERVICE
We recommend that you have your watch ser-
viced every three to five years. The best way to
do this is to bring your watch to an Authorized
Patek Philippe Retailer who will be happy to for-
ward it to our workshops for you. 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 watchmaker will completely disassemble the
movement and then inspect, clean, and lubri-
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 two
weeks. 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 as well as with an interchangeable solid-
metal back. Only our watchmakers at the Patek
Philippe workshops in Geneva are authorized to
replace this back.
PATEK PHILIPPE SEAL
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 aes-
thetic perfection of the timepiece. It covers the
technical, functional, and aesthetic factors, but
also rate accuracy, dependability, and customer
service quality. Additionally, it reflects the mak-
er's know-how and all other assets needed for the
development, production, and long-term main-
tenance of an extraordinary timekeeping instru-
ment.
