Welcome to the small circle of individuals who,
if we are to be absolutely recise, demand slightly more of
a watch than absolute recision. A reciation of a watch is
more than mere a reciation of the correct time. It is en-
thusiasm for an ingenious idea. For the inter lay between
recision and imagination. Between time and timeless-
ness. 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 recision but which also,
with every assing second, exert a fascination with the
great achievements of master craftsmanshi : a fascination
with new inventions of a technical, material or formal na-
ture, even if they are concealed in minute details that are
erha s not even visible. You are now the owner of a beau-
tiful new exam le of this IWC tradition. We would like to
congratulate you on your choice and send you our best
wishes for the time you will s end with your watch, which
erha s cannot be described with any greater accuracy
than it is here.
IWC Management

The technical refinements of the
Aquatimer Chronograph
Your IWC watch shows you the time in hours, minutes
and seconds, together with the date and the day. You can
use the integrated chronograph to measure any period of
time up to 12 hours in seconds, minutes and hours. Stop
times can be added together. The dive time is read off on
the external rotating bezel, which for safety reasons can
only be turned anticlockwise. The mechanical movement
with automatic winding has 25 jewels (synthetic rubies)
and a power reserve of approximately 44 hours when
fully wound. Your Aquatimer Chronograph is shockproof
and protected by a sapphire glass of hardness grade 9 on
ohs’ scale. Your watch is water-resistant 12 bar. To en-
sure that this extraordinary watch continues to perform
faultlessly in the future, it is essential to observe a few
important operating instructions.

Normal position
This watch has a screw-in crown. Screwing the crown in
to its normal position (X) prevents the inadvertent adjust-
ment 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 auto-
matically 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 max-
imum accuracy.
Date and day 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. Re-
lease the screw-in crown and pull it out to position 1. You
can now set the date by turning the crown to the right,
and the day by turning it to the left (rapid 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 move-
ment. 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 immediately 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.
Important: Although the watch is water-resistant in pos-
itions 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.
• Turn the crown to the left to advance the day display in
steps. Set the display to yesterday’s day.
• 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 be-
tween 12 midnight and 1 a.m.
• Now turn the hands forwards to the current time. If you
are setting the watch in the afternoon, you must turn
the hands past 12 (noon) again. 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 immediately when you restart the movement.

• Push the crown back to position 0 to start the move-
ment.
• 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 pos-
itions 0, 1 and 2, the crown should always be screwed in
again for normal use (position X).
Reading the time in the dark
The dial, the hour and minute hands, as well as the mark-
ing on the rotating bezel of your watch have luminescent
elements that allow you to read the time effortlessly
even in total darkness. The two luminescent elements at
12 o’clock serve as a reference point.

Reading the chronograph
Chronograph seconds hand: The scale for the central
chronograph seconds hand runs around the edge of the
dial.
Minute counter: The 30-minute scale with a slow jump-
ing hand is situated on the subdial at 12 o’clock. This
hand makes two complete revolutions in one hour.
Hour counter: The 12-hour scale with short lines for the
1/2-hour display with a continuous hand is situated on
the subdial at 6 o’clock.
Using the chronograph
Start: To start the chronograph, press the start/stop
button.
Stop: To stop the chronograph, press the start/stop
button again.
Reset: Press the reset button. This will reset all the
chronograph hands to zero.
Aggregate time recording: You can add stop times
together by pressing the start/stop button again after the
first measurement instead of the reset button.

Marking the start of a dive
The triangle on the rotating bezel can be aligned with the
minute hand by turning the rotating bezel anticlockwise.
The desired point in time (for example the time of enter-
ing the water at the start of the dive) can be set in this
way. You can read off the elapsed time (for example the
duration of the dive) on the rotating bezel. For safety rea-
sons, the rotating bezel can only be rotated in an anti-
clockwise direction. The rotating bezel is indexed audibly
and perceptibly in one-minute steps, and it is also legible
in the dark thanks to the luminescent markings.
If you are planning to use the watch to time dives, you
should e a certified open water diver and have the
water-resistance of your watch checked regularly y
an IWC service centre.
Cleaning the watch after diving
After diving – and especially after diving in seawater –
you should rinse your watch under running mains water.
This will prevent salt incrustation on the case, bracelet
and clasp.

Adjusting the metal racelet
If you have chosen a metal bracelet, you can easily adjust
it to the size of your wrist. You can make this adjustment
yourself by removing or adding individual bracelet links.
Taking the racelet apart and removing
individual links
Remove the bracelet from the case
as described and open the clasp by
pressing the button on the side. Lay
the bracelet with its top surface on a
firm base. Using the special tools
provided, you can now push down
the securing pin (1) at the desired point of separation and,
at the same time, displace the pivot pin laterally by ap-
proximately 3 millimetres (2) with the second special tool.
Now pull the protruding pivot pin
from the bracelet (3). The metal brace-
brace- let is now separated, and you can
adjust the length of the bracelet by
removing or adding individual links.

Determining racelet length
Place the watch with the bracelet
open around your wrist and estimate
the number of surplus bracelet links
that you can now remove from the
bracelet (as described above). If you
need to shorten the bracelet by sev-
eral links, you should remove the same number of links
from each half of the bracelet, if possible, to ensure that
the clasp can be worn more or less at the centre of the
wrist. We have included a short link in the clasp cover to
enable you to adjust the bracelet as accurately as pos-
sible to the size of your wrist. You can shorten your
brace-let by an intermediate amount by omitting this
bracelet link, and finer adjustment to the length of the
bracelet can be made in this way. Keep the surplus links
and the separating tools in a safe place for use in any
adjustment at another time.

Attaching the racelet
Attach the component parts of the
bracelet link to the connection point
and push the pivot pin into the brace-
let from the side (1).
Using the special tool provided, now
press the securing pin downwards (2)
and, at the same time, slide the pivot
pin back into the bracelet until it lies
flush (3). The securing pin must be
brought up flush with the upper edge
of the securing link. Please be sure to check that the pivot
pin is correctly seated.

Changing etween different types of racelet
Your IWC watch has a bracelet quick-change system*
that enables you to change the bracelet quickly and sim-
ply, without the use of tools.
To remove the bracelet, use your thumb
to push down the retaining lever (1)
on the underside of the horns.
While holding the lever down, slide the
connecting link out vertically from the
underside of the case (2).
* The Aquatimer bracelet quick-change system has been developed by
IWC under a patent licence from Cartier.

To attach the bracelet, push down the
two sides of the horns vertically to-
wards the lower side of the case and
into the recesses (3) until you hear and
feel the retaining lever engage.
When attaching the bracelet, you must ensure that the
horns are securely engaged to prevent the bracelet com-
ing off your wrist unintentionally.

Water-resistance
The water-resistance of IWC watches is stated in bar and
not in metres. etres, which are often used elsewhere in
the watch industry to indicate water-resistance, cannot
be equated with dive depth because of the test proced-
ures that are frequently used. Water-resistance shown in
metres provides no indication as to actual use of the
watch in the presence of moisture and wetness, and in or
under water. Recommendations for use in connection
with the water-resistance of your watch can be found on
the Internet at www.iwc.com/water-resistance. Your au-
thorized IWC Official Agent will also be pleased to pro-
vide you with information.
To ensure that your watch continues to function perfectly,
you should have it checked by an IWC service centre at
least once a year. Your watch should also be tested after
exposure to unusually harsh conditions. If the tests are
not carried out as stipulated, or if the watch is opened by
unauthorized persons, IWC will accept no warranty or li-
ability claims.
Recommendation: Your authorized IWC Official Agent
must carry out a water-resistance test whenever your
IWC watch is opened and serviced.
