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.

012

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.
