Maintenance
CERTIFICATE OF ORIGIN
Your watch is delivered with a certificate of origin
that indicates the movement and case numbers.
The certificate is valid only if it is dated, signed by
an Authorized Patek Philippe Retailer, and comple-
ted with your name. It guarantees the authenticity
of your watch and validates your warranty privileges
for a period of two years after the date of sale.
The unique movement and case numbers of each
watch are transcribed into the workshop journals.
With this information, you may have yourself en-
tered in the «Patek Philippe Register of Owners»
and will obtain the International Patek Philippe
Magazine free of charge.
PATEK PHILIPPE SEAL
As an all-encompassing hallmark of quality, the Patek
Philippe Seal applies to the entire watch, including
the movement, case, dial, hands, pushers, strap, and
clasp as well as to all other facets that contribute
to the precision and aesthetic perfection of the
timepiece. It covers the technical, functional, and
aesthetic factors, but also rate accuracy, dependa-
bility, and customer service quality. Additionally, it
reflects the maker's know-how and all other assets
needed for the development, production, and long-
term maintenance of an extraordinary timekeeping
instrument.
QUALITY CONTROL
The movements and completely assembled
watches are subject to a series of technical tests
and visual inspections to verify their rate accu-
racy, power reserve, reliability, water resistance,
and overall appearance. After it was assembled,
your manually wound watch will already have run
for 14 days before leaving the workshops; it fully
complies with the stringent criteria of the Patek
Philippe Seal.
RATE ACCURACY
The rate accuracy of Patek Philippe watches is
verified in several phases of manufacturing, both
with uncased and fully cased movements. The
final test is performed with a wrist motion simula-
tor 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.
