PORTOFINO HAND-WOUND MOON PHASE
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.
IWC MANAGEMENT
THE TECHNICAL
REFINEMENTS OF THE
PORTOFINO HAND-
WOUND MOON PHASE
Your IWC watch shows you the time in
hours, minutes and seconds, together
with the date, the moon phase and
the power reserve. Thanks to the
fibreoptic image guide, the date is
extremely easy to read. The mechan
ical movement has a power reserve of
approximately 8 days (192 hours) when
fully wound. Your Portofino Hand
Wound Moon Phase is protected by
an archededge sapphire glass of
hardness grade 9 on Mohs’ scale.
Your watch is waterresistant 3bar. To
ensure that this extraordinary watch

continues to perform faultlessly in the
future, it is essential to observe a few
important operating instructions.

NORMAL POSITION
With the crown in the normal position
(0), you can wind the watch by turning
the crown clockwise. In order to guar
antee maximum precision, always wind
the watch fully to the marking of 8 days
on the power reserve display.
DATE AND MOON PHASE
SETTING
If a month has fewer than 31 days, you
will need to set the date manually to
the first day of the following month.
Pull out the crown to position1. You
can now set the date by turning the
crown to the left, and the moon phase

display by turning it to the right (direct
advance). You should not use the
rapid-advance function between
8p.m. and 2 a.m. because the move-
ment automatically advances the
date and the moon phase display
during this period and the change
mechanism could be damaged.
TIME SETTING
Pull out the crown to position 2. This
will stop the movement. To set the time
accurately to the second, it is best to
stop the movement as the seconds
hand passes 60. Now move the minute
hand a few minute strokes beyond the
time to be set. Then position the minute
hand by moving it gently backwards
until it is exactly above the correct
minute stroke. This ensures that the
minute hand begins to move immedi
ately when you restart the movement.
To start the seconds hand, push in
the crown to position 0. When setting
the time, please be aware of the date
change, which always takes place at
12 midnight. If this change has already
taken place at 12 noon, you must move
the hands forwards by 12 hours.

SETTING YOUR WATCH
CORRECTLY
To set your watch correctly, proceed
as follows:
– Always wind the watch fully, to the
point at which you feel a distinct
resistance in the crown.
– Pull out the crown to position 1.
– Check the Internet to find out the
date of the last full moon. Set the
date display to that date by turning
the crown to the left.
– Turn the crown to the right to advance
the moon phase display until the full
moon can be seen in the dial opening
at 12 o’clock.
– Now make as many corrections, both
to the right and to the left, as corres
pond to the difference in the number
of days between yesterday’s date
and the date of the last full moon.
The watch should now display yes
terday’s date and yesterday’s moon
phase.
– Pull out the crown to position 2. This
will stop the movement. To set the
time accur ately to the second, it is
best to stop the movement as the
seconds hand passes 60.
– Turn the hands forwards until the date
display and the moon phase display
change to today’s date. The hands
will now be positioned between 12
midnight and 1 a.m.
– Now turn the hands forwards beyond
the approximate time. Then move
them backwards to the correct time.

INFORMATION ABOUT
MAGNETIC FIELDS
As a result of the ever greater prevalence
in recent years of very strong magnets
made from rareearth alloys (e.g. neo
dymiumironboron) – these are found
in objects such as loudspeakers,
mobile phones and fasteners on jewel 
lery as well as handbags– mechanical
watches are increasingly likely to come
into contact with such magnets and
become magnetized. This can lead
to the watch rate being perman ently
affected, a problem that can only be
resolved by a process of demagnet
ization carried out by a specialist. We
recommend that you keep your watch
away from such magnets.
If you are setting the watch in the
afternoon, you must turn the hands
past 12 (noon) again.
– Push the crown back to position 0 to
start the movement.
POWER RESERVE
DISPLAY
The power reserve display is divided
into eight days with continuous display.
The marking in the area of the last two
days tells you that the power reserve is
about to expire. You should then wind
the watch, since the precision can be
reduced in this area.
