USER MANUAL Pilot Chronograph 3777 IWC
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 PILOT'S WATCH CHRONOGRAPH
Your IWC watch shows you the time in hours, minutes and seconds, together with the date and the day. You can use the integrated 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 25 jewels (synthetic rubies) and a power reserve of approximately 44 hours when fully wound. Your Pilot's Watch Chronograph is water-resistant 6 bar and protected by a 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 has a double case. The soft-iron inner case provides protection against magnetic fields. 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
X - Normal position (screwed in)
0 - Winding position
1 - Date and day setting
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 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.
DATE AND DAY SETTING
If a month has fewer than 31 days, you will need to set the date manually to the first day of the following month. Release the screw-in crown and pull it out to position 1. You can now set the date by turning the crown to the right, and the day by turning it to the left (rapid 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 and the change mechanism could be damaged.
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 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. When setting the time, please be aware of the date change, which always takes place at 12 midnight. If this change has already taken place at 12 noon, you must move the hands forwards by 12 hours.
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.
- Turn the crown to the left to advance the day display in steps. Set the display to yesterday's day.
- 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 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.
- 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. The distinctive triangle at 12 o'clock serves as a reference point.
READING THE CHRONOGRAPH
Chronograph seconds hand: The scale for the central chronograph seconds hand runs around the edge of the dial.
Minute counter: The 30-minute scale with a slow jumping hand is situated on the subdial at 12 o'clock. This hand makes two complete revolutions in one hour.
Hour counter: The 12-hour scale with short lines for the 30-minute indication with a continuous hand is situated on the subdial at 6 o'clock.
USING THE CHRONOGRAPH
Start: To start the chronograph, press the start/stop button.
Stop: To stop the chronograph, press the start/stop button again.
Reset: Press the reset button. 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 button.
The metal bracelet has been designed so that you can easily adjust it to the size of your wrist. You can make this adjustment yourself by removing or adding individual bracelet links. Furthermore, for your personal convenience, this bracelet has an innovative fine adjustment system, permitting you to extend or reduce the length of the bracelet quite simply by up to 6 millimetres, depending on your needs. To increase the length of bracelet, press the button with the IWC logo and pull the bracelet slightly apart. To shorten it, push it together in the area of the clasp; here the button does not need to be pressed.
TAKING THE BRACELET APART
Open the folding clasp by pressing the button on the side. Lay the bracelet with the outside on a firm base. To avoid scratching the bracelet and base, place a cloth underneath the bracelet. Using the special tool provided, you can now push down the securing pin at the desired point of separation and, at the same time, slide the bracelet link outwards (1). Now slide the opposing external bracelet link away from the bracelet with both the pivot pins, without pushing down its securing pin (2). The bracelet is now separated (3).
DETERMINING HOW MANY LINKS TO REMOVE
Place the watch with the folding clasp closed around your wrist and use the overlap to estimate the number of surplus bracelet links that you can now remove as described below. If you need to shorten the bracelet by several links, we recommend removing the same number of links from each half of the bracelet, if possible, to ensure that the clasp can be worn more or less in the centre of the wrist.
Please observe the following recommendation: Generally the size of your wrist will increase during the course of the day, depending on temperature and physical exertion. Before you remove individual bracelet links, depending on the time of day you should have the fine adjustment system on the clasp closed (in the morning) or open (in the evening).
REMOVING INDIVIDUAL LINKS AND ATTACHING THE BRACELET
Repeat steps 1 to 3 at the distance from the first point of separation you have just determined.
Remove the unnecessary links and reassemble the shortened bracelet. When reassembling the central link, make sure that the outside is still facing downwards.
Reinsert the external link with both the pivot pins, which was removed at the beginning, back into the bracelet (4). Now you can slide the opposing external bracelet link back into the bracelet until it lies flush, by simultaneously pressing down its securing pin (5).
To finish, check that the securing pins are sitting correctly (6). These must be brought up flush with the upper edge of the external links.
Keep the surplus links and separating tool in a safe place for use in any adjustment at another time.
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
Leather is a natural and permeable material. Make sure, therefore, that the high-quality leather 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 PILOT'S WATCH CHRONOGRAPH
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.
Effective from November 2011. Technical specifications subject to change.
