BIG PILOT'S WATCH PERPETUAL CALENDAR
Welcome to the small circle of individuals who, if we are to be abso-
lutely 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
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
BIG PILOT'S WATCH PERPETUAL CALENDAR
Your IWC watch shows you the time in hours, minutes and seconds, the moon phase,
the day, the date, the month and the year in four digits, as well as the remaining
power reserve. The mechanical movement with automatic winding has a power
reserve of approximately 7days (168 hours) when fully wound. Your Big Pilot’s Watch
Perpetual Calendar is protected by a convex sapphire glass of hardness grade 9
on Mohs’ scale. Your watch is water-resistant 6bar. The engraved rotor in 18-carat
gold winds the watch in both directions of rotation via the Pellaton winding system. 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.

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 perpetual calendar 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 into position X and turning it to the right at the same time, it is
screwed down firmly again and secured.
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).

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. The crown must always be in position X when
you are wearing your watch.
SETTING THE CALENDAR
Release the screw-in crown and pull it out to position 1. You can now set the date
by turning the crown to the left (direct 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.
Please note:
– If the crown is turned too quickly, the display discs might not be positioned correctly
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 movement
is mechanically programmed and cannot be moved back in time without making 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 matches the correct date
once again. This makes sense if the date has been set only a few days ahead. Or, you
take your watch to your watchmaker, who will be able to adjust the movement to reset
the calendar. This is recommended in the event of larger maladjustments.

BIG PILOT'S WATCH PERPETUAL CALENDAR
TIME SETTING
Pull out the crown to position 2. This will stop the movement. To set the time accur-
ately 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 posi-
tion 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.
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.
Important:
– Under no circumstances must the hands be turned back between 8 p.m. and 2 a.m.
as this will result in maladjustment of the calendar.
– The hands must never be turned anticlockwise beyond 2 a.m.
– The crown must be pushed back into the normal position (X) and screwed in before
wearing the watch to avoid unintentional maladjustment of the calendar.

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 2 and turn the hands forwards to approximately 4.40a.m.
This ensures that the calendar mechanism is not in the middle of the automatic
switching phase and that you can also see the calendar displays easily.
– Push the crown to position 0 and pull it back to position 1.
– Slowly turn the crown to the left. The calendar now advances in steps. Set the display
to yesterday’s date, keeping an eye on the month and the year.
– Pull out the crown to position 2. This will stop the movement. To set the time accur-
ately 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.
– 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 movement.

BIG PILOT'S WATCH PERPETUAL CALENDAR
The entire calendar is now automatically set correctly. There is no need for you to know
the current phase of the moon or whether you are in a leap year. You do not even need
to set the day of the week. This simplified setting is very convenient, particularly if you
have not worn your IWC watch for a few days.
POWER RESERVE DISPLAY
The power reserve display is divided into 7 days with continuous display. The winding
mechanism winds the watch continuously while you are wearing it, and you can follow
the process on the power reserve indicator. The marking in the area of the last day tells
you that the power reserve is about to expire. You should then wind the watch by hand,
if necessary, since the precision can be reduced in this area.

MOON PHASE DISPLAY
1 — Full moon
2 — Waning moon
3 — New moon
4 — Waxing moon
The moon phase display is automatically set by the calendar so that it is always correct.
The transmission ratio is so precise that the display deviates by only a single day after
577 years.
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. The distinctive triangle
at 12 o’clock serves as a reference point.

CROSSING TIME ZONES AND THE INTERNATIONAL DATE LINE
WITH THE BIG PILOT'S WATCH PERPETUAL CALENDAR
Setting when crossing time zones:
– When crossing time zones in an easterly direction, you should simply set the time
forwards to the new local time.
– When crossing time zones in a westerly direction, you can set the hands of your watch
back to the actual time of day. When doing this, however, you must not move back
into the calendar’s automatic switching phase, i.e. beyond 2 a.m. If this situation
occurs when you are travelling west, you should set the local time of your destina-
tion before 8 p.m. You must not turn the hands back between 8 p.m. and 2 a.m.

BIG PILOT'S WATCH PERPETUAL CALENDAR
Setting when crossing the International Date Line:
– When crossing the International Date Line in a westerly direction (you enter the next
day, regardless of the time of day), simply turn the time forwards to the new local
time, and the date change will take place automatically.
– When crossing the International Date Line in an easterly direction (you enter the
previous day, regardless of the time of day), you must likewise set your watch
forwards to the new local time. However, your watch will now indicate the wrong date
(one day too many). This incorrect date indication can be corrected by resetting the
hands twice, by 12 hours on each occasion:
– Setting the watch back by 12 hours during the afternoon between 2 p.m.
and 8 p.m. will prevent the calendar from advancing at midnight.
– Setting the watch back another 12 hours the following morning between 2 a.m. and
11 a.m. will synchronize the date display with the local date.

INFORMATION ABOUT MAGNETIC FIELDS
As a result of the ever greater prevalence in recent years of very strong magnets made
from rare-earth alloys (for example neodymium-iron-boron) – these are found in objects
such as loudspeakers, jewellery and fasteners on mobile-phone cases and handbags –
mechanical watches are increasingly likely to come into contact with such magnets and
be magnetized. This can lead to the watch rate being permanently affected, a problem
that can only be resolved by a process of demagnetization carried out by a specialist.
We recommend that you keep your watch away from such magnets.
Watches with a soft-iron inner case provide a higher level of protection against magnetic
fields and far exceed the requirements of DIN standard 8309. Nevertheless, it is still
possible for the watch movement to be magnetized in the close proximity of very strong
magnets. We therefore recommend that watches with a soft-iron inner case also be kept
away from direct contact with strong magnets.
Should there be a sudden change in the precision of your timepiece, please contact
an authorized IWC Official Agent to have your watch checked for magnetism.

WATER-RESISTANCE
The water-resistance of IWC watches is stated in bar and not in metres. Metres, which
are often used elsewhere in the watch industry to indicate water-resistance, cannot be
equated with dive depth because of the test procedures 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 authorized IWC Official Agent will also be pleased
to provide 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 liability
claims.
Recommendation: Your authorized IWC Official Agent must carry out a water-resis-
tance test whenever your IWC watch is opened and serviced.

NOTE
If your watch has a strap made of leather, textile or rubber with a leather or textile
inlay, make sure that the high-quality strap does not come into contact with water, oily
substances, solvents, cleaning agents or cosmetic products. This way you can prevent
discoloration and premature ageing of the material.
HOW OFTEN SHOULD MY WATCH BE SERVICED?
The optimalservicecycle for your IWC timepiece is exclusive to your watch and
unique lifestyle. The necessaryintervalbetweenservices will be determined by your
individual wearing habits;frequency of wear, your environment/s, and the intensity of
physical activity you engage in. Your fine mechanical timepiece is an extension of
yourself and will run well for as long and smoothly as it is treated. Therefore, we
simply recommend you to continue wearing your watch for as long as pleases you and
to only entrust it for aserviceif you notice a deviation from the regular performance,
function or timekeeping. It will then be our pleasure to reinstate the premium
performance with the suitableservice.
