PORTUGIESER PERPETUAL CALENDAR DIGITAL DATE-MONTH
EDITION “75TH ANNIVERSARY”
Welcome to the small circle of individuals who, if we are to be
absolutely precise, demand slightly more of a watch than absolute precision. Appreci-
ation 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 per-
haps cannot be described with any greater accuracy than it is here.

THE TECHNICAL REFINEMENTS OF THE
PORTUGIESER PERPETUAL CALENDAR DIGITAL DATE-MONTH
EDITION “75TH ANNIVERSARY”
Your IWC watch shows you the time in hours, minutes and seconds with hands as
well as the date and the month in a large digital display and 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. Stop times can be added together. The mechanical
movement with automatic winding has a power reserve of approximately 68 hours
when fully wound. The engraved rotor made of 18-carat red gold winds the watch in
both directions of rotation via the IWC double-pawl winding system. Your Portugieser
Perpetual Calendar Digital Date-Month Edition “75th Anniversary” is protected by an
arched-edge sapphire glass of hardness grade 9 on Mohs’ scale. The glass is retained
securely in the case at low pressure, for example when a drop in air pressure occurs
at extreme altitudes. Your watch is water-resistant 3 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.

FUNCTIONS OF THE CROWN
0 — Normal position (screwed in)
1 — Setting the calendar
2 — Time setting
NORMAL POSITION
With the crown in the normal 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 0 when
you are wearing your watch.

SETTING THE CALENDAR
Pull the crown out to position 1. In this position, you can use the direct-advance func-
tion 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 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 2016, 2020, 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.
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 before wearing the watch
to avoid unintentional adjustment of the calendar.

SETTING YOUR WATCH CORRECTLY
To set your watch correctly, proceed as follows:
– 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 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 correct time. If you are setting the watch in the
afternoon, you must turn the hands past 12 (noon) again.
– Push the crown back to position 0 to start the movement.

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.
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 measurement 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.
Aggregate time recording: You can add stop times together by pressing the start/stop
push-button again after the first measurement instead of the reset/flyback push-but-
ton.

CROSSING TIME ZONES AND THE INTERNATIONAL DATE LINE
WITH THE PORTUGIESER PERPETUAL CALENDAR
DIGITAL DATE-MONTH EDITION “75TH ANNIVERSARY”
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
destination before 8 p.m. You must not turn the hands back between 8 p.m. and
2 a.m. This is because the calendar does not move backwards by one day when
the hands are turned back beyond midnight, but remains on the same day. If you
go past the end of the calendar’s switching phase (i.e. beyond 2 a.m.) when turning
the hands back, you run the risk of the calendar advancing by one day for a second
time and thus indicating one day too many.

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 for-
wards 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 by 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 car-
ried 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 mag-
netic 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 Inter-
net 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-resist-
ance 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.
SERVICING YOUR PORTUGIESER PERPETUAL CALENDAR
DIGITAL DATE-MONTH EDITION “75TH ANNIVERSARY”
Although the parts in this watch are all manufactured from top-quality materials, a
number of components are subject to natural wear and tear. It is particularly important
to ensure that the points at which wear occurs are always well lubricated and that oil
contaminated by metal abrasion is regularly removed. For this reason, we recommend
that you have your watch serviced approximately every 5 years. Please contact an
authorized IWC Official Agent or send your watch directly to the IWC Customer Service
Department in Schaffhausen.
