INGENIEUR CHRONOGRAPH
Welcome to the small circle of individuals who, if we are to be
absolutely precise, demand slightly more of a watch than absolute precision. Appre-
ciation 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
INGENIEUR CHRONOGRAPH
Your IWC watch shows you the time in hours, minutes and seconds, together with
the date. You can use the integrated chronograph to measure any period of time in
seconds, minutes and hours. Stop times can be added together. The mechanical
movement with automatic winding has a power reserve of approximately 68 hours
when fully wound. The engraved rotor winds the watch in both directions of rotation
via the IWC double-pawl winding system. Your Ingenieur Chronograph is protected by
a sapphire glass of hardness grade 9 on Mohs’ scale. Your watch is water-resistant
12 bar. To ensure that this extraordinary watch continues to perform faultlessly in the
future, it is essential to observe a few important operating instructions.

FUNCTIONS OF THE CROWN
X — Normal position (screwed in)
0 — Winding position
1 — Date setting
2 — Time setting
NORMAL POSITION
This watch has a screw-in crown. Screwing the crown in to its normal position (X)
prevents the inadvertent adjustment of the time or date and also acts as a double
seal to prevent water from seeping into the case. To release the crown, unscrew it by
turning it to the left, where it automatically assumes position 0, the winding position.
By depressing the crown in position X and turning it to the right at the same time, it is
screwed down firmly again and secured.

WINDING POSITION
With the crown in the winding position (0), you can also wind the automatic movement by
hand. A few revolutions of the crown are enough to start the movement. However, it is bet-
ter to wind the watch by turning the crown through approximately 20 revolutions as this will
ensure maximum accuracy. The crown must always be in position X when you are wearing
your watch.
DATE 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. Release the screw-in crown and pull it out to position 1.
You can now set the date by turning the crown to the right (direct advance). You should
not use the rapid-advance function between 8 p.m. and 2 a.m. because the movement
automatically advances the date during this period
TIME SETTING
Pull out the crown to position 2. This will stop the movement. To set the time accurate-
ly to the second, it is best to stop the movement as the seconds hand passes 60. You
can now set the time by turning the crown and positioning the minute hand exactly
above the minute stroke. 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.
Important: Although the watch is water-resistant in positions 0, 1 and 2, the crown
should always be screwed in again for normal use (position X).

SETTING YOUR WATCH CORRECTLY
To set your watch correctly, proceed as follows:
– Release the crown by turning it to the left.
– Wind the movement (approximately 20 revolutions of the crown).
– Pull out the crown to position 1.
– Turn the crown to the right to advance the date display in steps. Set the display to
yesterday’s date.
– 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.
– Turn the hands forwards until the date display changes to today’s date. The hands
will now be positioned between 12 midnight and 1 a.m.
– Now turn the hands forwards to the correct time. 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.
– Now push the crown to position X and secure it by simultaneously turning it to the
right.
Important: Although the watch is water-resistant in positions 0, 1 and 2, the crown
should always be screwed in again for normal use (position X).
