WATER RESISTANCE
The case of your Calatrava Travel Time is fitted with different
types of seals that protect the movement against dust, humidity,
and risk of damage if submerged. However, if your watch
receives a blow on the crown or the crystal, its water resistance
may be impaired.
If your watch has a leather strap, we recommend that you
avoid exposing it to water altogether.
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. You can
then be assured that your watch will be inspected and serviced
by a qualified Patek Philippe watchmaker in Geneva or at an
Authorized Service Center.
The watchmaker will disassemble the movement and then
inspect, clean, and lubricate all the individual parts prior to
reassembly. All functions of the watch will be thoroughly tested
and the escapement regulated if necessary. Finally, its adjust-
ments and rate accuracy will be monitored for a 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 service issues, please
contact your nearest Authorized Patek Philippe Retailer or
our International Customer Service Department in Geneva.
