DA VINCI PERPETUAL CALENDAR CHRONOGRAPH
Welcome to the small circle of
individuals who, if we are to be abso-
lutely precise, demand slightly more
of a watch than absolute precision.
Appreciation of a watch is more than
mere appreciation of the correct time.
It is enthusiasm for an ingenious idea.
For the interplay between precision
and imagination. Between time and
timelessness. Between boundaries
and infinity. Between laws to which
the entire world is subject, and taste,
which cannot be dictated to anyone.
That is why, since 1868, we have been
devoting rather more of our time to
watches that must not only run with
absolute precision but which also, with

every passing second, exert a fas-
cination with the great achievements
of master craftsmanship: a fascination
with new inventions of a technical,
material or formal nature, even if they
are concealed in minute details that are
perhaps not even visible. You are now
the owner of a beautiful new example
of this IWC tradition. We would like to
congratulate you on your choice and
send you our best wishes for the time
you will spend with your watch, which
perhaps cannot be described with any
greater accuracy than it is here.

THE TECHNICAL
REFINEMENTS OF THE
DA VINCI PERPETUAL
CALENDAR CHRONOGRAPH
Your IWC watch shows you the time
in hours, minutes and seconds, the
moon phase, the day, the date, the
month and the year in four digits, as
well as the remaining power reserve.
The mechanical movement with auto-
matic winding has a power reserve
of approximately 68 hours when fully
wound. Your Da Vinci Perpetual Cal-
endar Chronograph is protected by an
arched-edge sapphire glass of hard-
ness grade 9 on Mohs’ scale. Your

watch is water-resistant 3 bar. The
engraved rotor made of 18-carat gold
winds the watch in both directions of
rotation via IWC’s double-pawl wind-
ing. In addition to the uniqueness of
its functions, it is the display’s legibil-
ity and the ease with which it can be
used that distinguishes this watch from
all other complicated timepieces. To
ensure that this extraordinary watch
continues to perform faultlessly in the
future, it is essential to observe a few
important operating instructions.
