WELCOME
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 ingeni-
ous 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 fascination
with the great achievements of master craftsmanship: a fas-
cination 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 beau-
tiful new example of this IWC tradition. We would like to con-
gratulate 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.

Ingenieur Perpetual Calendar Digital Date-Month is protected
by a convex sapphire glass of hardness grade 9 on Mohs’
scale. Your watch is water-resistant to 12 bar. In addition to
the uniqueness of its functions, it is the display’s legibility and
the ease with which it can be used that distinguishes this
watch from 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.
THE TECHNICAL REFINEMENTS OF THE
INGENIEUR PERPETUAL CALENDAR
DIGITAL DATE-MONTH
Your IWC watch shows you the time in hours, minutes and
seconds with hands, the date and the month in a large digital
display as well as the leap year. You can use the integrated
flyback chronograph to measure any period of time up to
12hours in seconds, minutes and hours. Recorded times can
be added together. The mechanical movement with automatic
winding has a power reserve of approximately 68hours when
fully wound. The rotor winds the watch in both directions
of rotation via the IWC double-pawl winding system. Your

NORMAL POSITION
This watch has a screw-in crown. Screwing the crown into 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 pos-

SETTING THE TIME AND CALENDAR
If you have not worn your watch for more than 68 hours, the
watch will normally stop at midnight, as the changeover of
the calendar uses a great deal of energy.
Warning:
If your watch has stopped between 10 p.m. and 2 a.m.,
you should on no account alter the date using the rapid-
advance date display with the crown in position 1. This
would result in damage to a component in the calendar mech-
anism which would require repair by a watchmaker.
ition 0, the winding position. By depressing the crown into
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 recommended to wind the watch by turning the crown
through approximately 20 revolutions as this will ensure
maximum precision.

a further 12 hours. Once the hour and minute have been set
to the correct time using this process, push back the crown
to position 0 to start the seconds hand. 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.
SETTING THE CALENDAR
Pull the crown out to position 1. In this position, you can use
the direct-advance function to move the calendar forwards
one step at a time by turning the crown slowly to the right.
The calendar must not be adjusted between 10 p.m. and 2
a.m. The leap year display has four positions: “1”, “2”, “3” and
TIME SETTING
Release the screw-in crown. This makes it jump to position 0.
We recommend winding the movement at least 20 times with
the crown in this position. Then pull the crown out to position
2 in order to set the hour and minute hands to approximately
6 a.m. To set the time accurately to the second, it is best to
stop the movement as the small seconds hand passes 60.
Push back the crown to position 1. In this position, you can
safely set the date to the previous day. If you now pull the
crown out to position 2, you can set the exact time in hours
and minutes. If the date does not jump to today’s date when
it passes 12 o’clock, you must wind the hour hand forward by

Warning:
In order to protect the watch from the ingress of water, the
crown must always be in position X (screwed in) and should
only be pulled out to position 1 or 2 when setting the watch.
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.
“L”. “L” stands for “leap year”. If the current year is a leap year
(i.e. the year is divisible by 4 – e.g. 2016, 2020), you must
adjust the calendar so that the leap year display shows “L”.
“1” corresponds to the first year after a leap year, “2” to the
second and “3” to the third. Once set correctly, the perpetual
calendar will automatically show the correct date at all times.
You do not need to do anything until 1March 2100 when
you must manually move the calendar forwards by 1 day.
Although 2100 is divisible by 4, it is not a leap year accord-
ing to the Gregorian calendar.

USING THE CHRONOGRAPH
Start: To start the chronograph, press the start/stop push-
button.
Flyback: You can start recording a new time immediately,
even when the chronograph is running. Simply depress the
reset/flyback push-button fully, as far as it will go. All three
chronograph hands are reset to zero, and a new measure-
ment is started as soon as the push-button is released.
Stop: To stop the running chronograph, press the start/stop
push-button.
Reset: Depress the reset/flyback push-button fully, as far as
it will go. This will reset all the chronograph hands to zero.
READING THE CHRONOGRAPH
Chronograph seconds hand: The scale for the central
chronograph seconds hand runs around the edge of the dial.
Minute and hour counters: The subdial at 12 o’clock has two
hands, which run continuously and show the elapsed time
on a 12-hour and a 60-minute scale. The hour and minute
counters can be read like a standard analogue time display.
In other words, one revolution of the minute counter is equal
to 60 minutes, and one revolution of the hour counter is equal
to 12 hours.
