Welcome to the small circle of people who de-

mand more from their watch than mere accuracy. Enjoy-

ment of your watch is more than just the enjoyment of the

precise time. It is enthusiasm for an amazing concept. For

the interplay between precision and imagination. Between

time and timelessness. Between boundaries and infinity.

Between laws that the whole world must obey and taste,

which cannot be dictated to anyone. That is why, since

1868, we have been devoting rather more of our time to

the watch; not only must a watch run accurately, but a

fascination with great achievements of craftsmanship

must also emanate from it at every instant through new in-

ventions of a technical, material or design nature, even if

they are concealed in the smallest detail, which is

perhaps not even visible. You are now the owner of a

beautiful new example of this IWC tradition. We should

like to congratulate you most sincerely on your choice,

and we send you our best wishes for the time that you

will spend with your watch, which perhaps cannot be

described with any greater accuracy than it is here.

Technical refinements of the Pilot’s Watch

Chrono-Automatic Edition TOP GUN

Your IWC watch shows you the time in hours, minutes and

seconds as well as the day and date. With the integrated

chronograph, you can measure any length of time up to

12 hours in seconds, minutes and hours. The mechanical

movement with automatic winding has 25 jewel bearings

(synthetic rubies) and has a power reserve of at least

44 hours when fully wound. The watch case is water-

resistant 6 bar and is protected by a sapphire glass of

hardness grade 9, which is secured against displacement

from a drop in air pressure at extreme altitudes. Your

IWC watch has a double case; the soft iron inner case

assures optimal protection against magnetic fields.

To ensure that this extraordinary watch continues to

perform its tasks in future, it is essential to follow a

few important operating instructions.

Normal position

This watch has a screw-in crown. The screw-in connec-

tion (normal position, position X) prevents unintentional

adjustment of the time or the date, and the watch case

has double protection against penetrating water. To

release the secure crown, unscrew it by rotating it to the

left, where it automatically assumes position 0, the wind-

ing position. By depressing the crown in position X and

rotating it to the right at the same time, it is screwed

down firmly again and secured.

Winding position

In the winding position (position 0), you can also wind

the automatic movement by hand. The movement will start

after only a few revolutions of the crown. However, it is

better to wind the movement fully with about 30 revolutions

of the crown, as maximum accuracy and a power reserve

of about 44 hours will then be assured, even after taking off

the watch.

Setting the date and the day

If a month has fewer than 31 days, you must set the date

by hand 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 rotating it to the right, and the day by

rotating it to the left (quick setting). You must not perform

quick setting between 20.00 and 2.00, since the date is

changed automatically by the movement during this time

period and the change mechanism could be damaged.

Setting the time

Pull out the crown to position 2. This will stop the move-

ment. For setting the time accurately to the second, it is

best to bring the movement to a stop as the seconds

hand passes over 60. You should now move the minute

hand a few minute lines beyond the time to be set.

Then position the minute hand by moving it gently back-

wards until it is exactly above the correct minute line.

By adopting this procedure, you will ensure that the minute

hand begins to move without any delay 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

midnight (24.00). If this change has already taken place at

12.00 noon, you must turn the hands forwards through

12 hours.

Setting your watch correctly

You can set your watch correctly as follows:

• Release the crown by turning it to the left.

• Wind the movement until it is fully wound (ca. 30 rota-

tions of the crown).

• Pull out the crown to position 1.

• Turning the crown to the right will change the date

indicator in steps. Set it to yesterday’s date.

• Turning the crown to the left will change the day indi-

cator in steps. Set it to yesterday’s day.

• Pull out the crown to position 2, which will stop the

movement.

• Turn the hands forwards until the date indicator

changes to today’s day. The hands will now be set

between 0.00 and 1.00.

• Now turn the hands forwards to the precise time;

you will have to move the hands past 12.00 (noon) once

again in the afternoon.

• Push in the crown to position 0 to restart the move-

ment.

• Now push in the crown to position X and secure it by

turning it to the right at the same time.

Important: Although the watch is still water-resistant in

positions 0, 1 and 2, the crown must always be screwed in

again (position X) for normal use.
