If you notice that your watch exhibits such ir regu-
larities, please do not hesitate to take it to an
Authorized Patek Philippe Retailer or an authorized
Service Center where no effort will be spared to
assure that it is adjusted to meet your expectations.
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. Nonetheless, we recommend
that you prevent direct contact with water if your
watch has a leather strap.
service
We recommend that you have your watch serviced
every five years. The best way to do this is to bring
your watch to an Authorized Patek Philippe Retailer
who will be happy to forward 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 or at an Authorized Service Center.
The 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 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.
