If you notice that your watch exhibits such

irregularities, 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
and a screw-down crown to protect the move-
ment against the ingress of dust and moisture
and to prevent damage if it is immersed in the
water. Nonetheless, we recommend that you pre-
vent 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.
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
hands of a qualified Patek Philippe watchmaker in
Geneva or at an Authorized Service Center.
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
