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.
It is advisable to have a water-resistance test car-
ried out every year on your watch. This is a simple
procedure that takes only a few minutes at a prop-
erly equipped point of sale.
changing the caseback
If your watch was delivered with two interchangea-
ble case backs, please note that only an Authorized
Patek Philippe Retailer or an Authorized Service
Center is qualified to exchange the case backs.
service
We recommend that you have your watch ser-
viced every three to five years. For this purpose,
we suggest that you bring or send your watch to an
Authorized Patek Philippe Retailer or an Authorized
Service Center. This gives you the assurance that
your watch will be entrusted to the hands of a
qualified Patek Philippe watchmaker in Geneva or
at one of the Authorized Service Centers.
The watchmaker will completely disassemble the
movement and then clean and inspect all parts
and lubricate them in the reassembly process. 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.
