INGENIEUR CONSTANT-FORCE 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. 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
fascination 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 per-
haps cannot be described with any greater accuracy than it is here.

THE TECHNICAL REFINEMENTS OF THE INGENIEUR
CONSTANT-FORCE TOURBILLON
Your IWC watch shows you the time in hours, minutes and seconds, together with
the moon phases in both hemispheres, the time left until the next full moon and the
power in reserve. The mechanical movement with automatic winding has a power
reserve of approximately 96 hours when fully wound. Your Ingenieur Constant-Force
Tourbillon is protected by a sapphire glass of hardness grade 9 on Mohs’ scale. Your
watch is water-resistant 12bar. Furthermore, it is equipped with a minute tourbillon, a
unique micro mechanism, which minimizes the effect of gravity on the rate precision.
The constant-force mechanism, which is housed directly in the tourbillon, ensures
consistent amplitude over at least 2 days. This is indicated by the one-second jumps
of the seconds hand in the tourbillon. If the energy in the two barrels is insufficient
to maintain the constant-force mechanism, the watch rate automatically switches to
2.5 Hertz. This can be seen in the fact that the seconds hand on the tourbillon is now
moving constantly. This rate corresponds to that of a standard tourbillon.To ensure
that this extraordinary watch continues to perform faultlessly in the future, it is essen-
tial to observe a few important operating instructions.

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 the moon phase indication 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 wind the movement by hand. A
few revolutions of the crown are enough to start the movement. However, it is better
to wind the watch by turning the crown to the point at which you feel a distinct resist-
ance as this will ensure maximum accuracy. The crown must always be in position X
when you are wearing your watch.
MOON PHASE SETTING
Although the watch is limited to a 12-hour display, the movement makes a distinc-
tion between 12 noon and 12 midnight. The moon phase moves on 1 day at midnight
every day (like a date switch). If your watch has stopped, the moon phase needs to
be adapted to the current moon position. To do this, move the crown into position 1
and adjust the moon phase by rotating the crown to the left or right. You should not
use the rapid-advance function between 8 p.m. and 2 a.m. because the movement
automatically advances the moon phase during this period.
Procedure: consult the daily press or another source to find the current moon phase
(e.g. the Internet, lunar calendar) and set the countdown display to the number of
days to the next full moon.

TIME SETTING
Pull out the crown to position 2. You can now set the time by turning the crown.
Afterwards, push in the crown to position 0 and secure it in position X by tightening
the screw. When setting the time, please be aware of the moon phase 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).
POWER RESERVE DISPLAY
The power reserve display is divided into twelve sections of 8 hours each. To achieve
maximum accuracy, wind your watch fully every day.
READING THE TIME IN THE DARK
Both the dial and the hour and minute hands of your watch have luminescent elements
that allow you to read the time effortlessly, even in total darkness.
