QUALITY CONTROL
The movements and completely assembled watches
are subject to a series of technical tests and visual
inspections to verify their rate accuracy, winding
speed, power reserve, reliability, water resistance,
and overall appearance. Once assembled, your self-
winding watch will run for several weeks before
leaving the workshops; it fully complies with the
stringent criteria of the Patek Philippe Seal.
ACCURACY
The rate accuracy of Patek Philippe watches is ver-
ified in several phases of manufacturing, both with
uncased and fully cased movements. The final test
is performed with a wrist motion simulator and
the results must conform to the following Patek
Philippe precision benchmarks:
The rate accuracy of calibers with a diameter of 20 mm
or larger must range within -3 and +2 seconds per
24 hours.
The precision of a watch is determined by how accu-
rately it keeps the time. A watch that is fast or slow
is considered precise if the amount by which it is
fast or slow remains constant. Such a deviation can
be easily corrected. Consequently, the final test of
accuracy takes place on your wrist. Your tempera-
ment or the nature of your physical activities can
cause slight irregularities. Fluctuations in position,
temperature, or air pressure, the presence of mag-
netic fields (as produced by most electronic devices,
metal detectors, household appliances, etc.) as well
as vibrations and other factors may also affect its
accuracy. If you notice that your watch exhibits
14
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
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.
SERVICE
We recommend that you have your watch serviced
every three to five years. With this in mind, we
suggest that you take or send your watch to an
Authorized Patek Philippe Retailer or an Author-
ized 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 an Authorized Service Center.
