AQUATIMER PERPETUAL CALENDAR DIGITAL DATE-MONTH
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
perhaps cannot be described with any greater accuracy than it is here.

THE TECHNICAL REFINEMENTS OF THE
AQUATIMER 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 sec-
onds, minutes and hours. Stop times can be added together. The dive time is read off
on the internal rotating bezel, which for safety reasons can only be turned anticlock-
wise. The mechanical movement with automatic winding has a power reserve of ap-
proximately 68 hours when fully wound. The rotor winds the watch in both directions
of rotation via the IWC double-pawl winding system. Your watch is water-resistant
10 bar and protected by a sapphire glass of hardness grade 9 on Mohs’ scale. In add-
ition 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.

FUNCTIONS OF THE CROWN
X — Normal position (screwed in)
0 — Winding position
1 — Setting the calendar
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 better to wind the watch by turning the crown through approximately 20 revolutions
as this will ensure maximum accuracy.

SETTING THE CALENDAR
Release the screw-in crown and pull it 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 turn-
ing the crown slowly to the right. The calendar must not be adjusted between 8 p.m.
and 2 a.m.
The leap year display has four positions: “1”, “2”, “3” and “L”. “L” stands for “leap
year”. If the current year is a leap year (i.e. the year is divisible by 4, for example 2012,
2016, etc.), 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 need do nothing until 1 March 2100, when you must manually move the
calendar forwards by one day. Although 2100 is divisible by 4, it is not a leap year
according to the Gregorian calendar.
Please note:
– If the crown is turned too quickly, the display discs might not be positioned cor-
rectly in the display window. Generally, such a default is automatically corrected by
the movement when the calendar advances within the following 24 hours. Should
this not be the case, the movement needs to be reset by an IWC watchmaker.
– You must not move the calendar beyond the correct date. The complicated move-
ment is mechanically programmed and cannot be moved back in time without mak-
ing a professional adjustment to the movement. However, if you do move the date
forwards beyond the correct date, you have two options: You can either pull out
the crown to position 2 to stop the movement until the calendar setting once again
matches the correct date. This makes sense if the date has been set only a few
days ahead. Or, you can slowly advance the calendar by 4 years until you reach the
correct date. Alternatively, you can entrust this operation to your watchmaker.

TIME SETTING
Pull out the crown to position 2. This will stop the movement. To set the time ac-
curately 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. Moving the hands forwards past midnight causes the
calendar to switch to the following day. When advancing the calendar, you can follow
and observe the automatic switching sequence.
In order to avoid incorrect adjustment of the mechanism, you should not move the
hands back between 8 p.m. and 2 a.m. This is because the calendar is disconnected
from the movement when the hands are turned back and will not move backwards. To
start the seconds hand, push in the crown to position 0.
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.
