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 com-
pleted with your name. It guarantees the authen-
ticity 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 entered 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 accu-
racy, dependability, 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.
