—Welcome to the small circle of individuals who, if we are to be

absolutely 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.

IWC MANAGEMENT

THE TECHNICAL REFINEMENTS OF THE INGENIEUR PERPETUAL CALENDAR DIGITAL DATE-MONTH

Your IWC watch shows you the time in hours, minutes and seconds with hands, the date and the month in a large digital display as well as 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 rotor in the form of a Spitfire winds the watch in both directions of rotation via the IWC double-pawl winding system. Your Ingenieur Perpetual Calendar Digital Date-Month is protected by a sapphire glass of hardness grade 9 on Mohs' scale. Your watch is water-resistant 12 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.

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 date 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 in position X and turning it to the right at the same time, it is screwed down firmly again and secured.

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.

SETTING THE CALENDAR

Release the screw-in crown and pull it out to position 1. In this position, you can use the direct-advance function 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 2012, 2016, 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 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 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 accurately 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.

In order to avoid incorrect adjustment of the mechanism, you should not move the hands back between 8 p.m. and 2 a.m. This is because the calendar is disconnected from the movement when the hands are turned back and will not move backwards. To start the seconds hand, push in the crown to position 0.

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).

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 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 accurately 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.
• Now push the crown to position X and secure it by simultaneously turning it to the right.

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).

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.

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 button.

Flyback: You can start recording a new time immediately, even when the chronograph is running. Simply depress the reset/flyback 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 button is released.

Stop: To stop the running chronograph, press the start/stop button.

Reset: Depress the reset/flyback 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 button again after the first measurement instead of the reset/flyback button.

CROSSING TIME ZONES AND THE INTERNATIONAL DATE LINE WITH THE INGENIEUR PERPETUAL CALENDAR DIGITAL DATE-MONTH

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 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 by another 12 hours the following morning between 2 a.m. and 11 a.m. will synchronize the date display with the local date.

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-resistance 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 INGENIEUR PERPETUAL CALENDAR DIGITAL DATE-MONTH

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 five years. Please contact an authorized IWC Official Agent or send your watch directly to the IWC Customer Service Department in Schaffhausen.
