Welcome to the small circle of individuals who, if we are to be ab-
solutely 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 enthusiasm for an ingenious idea. For the inter lay between recision
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 devot-
ing 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 in-
ventions of a technical, material or formal nature, even if they are concealed
in minute details that are erha s not even visible. You are now the owner of
a beautiful 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 accur-
acy than it is here.

The technical re inements o the
Portuguese 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 62 jewels (synthetic rubies) and a power reserve of approxi-
mately 7 days (168 hours) when fully wound. Your Portuguese Perpetual
Calendar is protected by a convex sapphire glass of hardness grade 9 on
Mohs’ scale. Your watch is water-resistant 3 bar. The engraved rotor with its
18-carat gold medallion winds the watch in both directions of rotation via the
Pellaton winding mechanism. In addition to the uniqueness of its functions,
it is the display’s legibility and the ease with which it can be used that distin-
guishes this watch from all 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.

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.
Quick-setting the calendar
Pull out the crown to position 1. In this position, you can use the rapid-advance
function to move the calendar forwards one step at a time by turning the crown
slowly to the left. The calendar must not be adjusted between 8 p.m. and
2 a.m.

Please note:
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. r, you must 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.
Time setting
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. Now move the minute hand a few minute strokes 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 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 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 2 and turn the hands forwards to approxi-
mately 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 accurately to the second, it is best to stop the movement as the sec-
onds 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.
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 con-
venient, particularly if you have not worn your IWC watch for a few days.
