PORTUGIESER PERPETUAL CALENDAR TOURBILLON
Welcome to the small
circle of individuals who, if we are to
be absolutely 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 imagin ation. 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 fascin
ation with the great achievements of
master craftsmanship: a fascin ation
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 trad ition. 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.

Your IWC watch shows you the time in
hours and minutes, the moon phase,
the day, the date, the month and the
year in four digits, as well as the remain
ing power reserve. The mechanical
movement with automatic winding
has a power reserve of approximately
7 days (168 hours) when fully wound.
Your Portugieser Perpetual Calendar
Tourbillon is protected by an arched
edge sapphire glass of hardness
grade 9 on Mohs’ scale. Your watch
is waterresistant 3 bar. The engraved

rotor made of 18carat red gold winds
the watch in both directions of rotation
via the Pellaton winding system. Your
watch is equipped with a flying minute
tourbillon, a unique micro mechanism,
which minimizes the effect of gravity
on the accuracy. The tourbillon, an
invention made in the aftermath of the
French Revolution, has always been
regarded as the ultimate challenge
in the quest for absolute mechanical
watchmaking precision. More specific
ally, the purpose of the mechanism is
to counterbalance the onesided pull
of the earth’s gravity on the balance.
This is because the residual gravita
tional error of the balance influences
the accuracy, depending on the pos
ition of the watch. Fortunately, there

is a way to overcome this problem
caused by one of the basic laws of
physics: the balance, the pallets and
the escape wheel are mounted in
a minute cage that rotates around
itself once every minute. In this way,
the effect of the gravitational error is
practically elim inated. To ensure that
this extraordinary watch continues to
perform faultlessly in the future, it is
essential to observe a few important
operating instructions.
