Frequently Asked Questions - Ingenieur Double Chronograph Titanium 3865 IWC

How do I set the date and day on my IWC Ingenieur watch?

Unscrew the crown by turning it to the left, then pull it to position 1. Turn the crown to the right to set the date, and to the left for the day of the week. Important: never perform this adjustment between 8 PM and 2 AM, as the automatic change mechanism could be damaged.

How do I use the double chronograph?

To start, press the start/stop pusher. To record an intermediate time, press the rattrapante pusher: the rattrapante seconds hand stops while the timing continues. Press this pusher again to let the rattrapante hand catch up to the chronograph hand. To stop, press start/stop again. To reset, press the reset pusher. Note: the rattrapante hand only resets to zero if you activate the rattrapante pusher after stopping.

What is the water resistance of my watch?

Your watch is water-resistant up to 12 bar (approximately 120 meters). However, water resistance may decrease over time; have the watch checked every year by an authorized IWC dealer. Reminder: the crown must be screwed in (position X) before any contact with water.

How do I manually wind the movement?

Unscrew the crown (position 0). Turn it about 20 times clockwise to fully wind the movement. Manual winding is useful if the watch has not been worn for some time.

What should I do if my watch stops?

If the watch stops, it likely needs to be wound. Follow the manual winding procedure (about 20 crown turns). If it does not restart, contact an authorized IWC service. Also ensure the crown is properly screwed down after adjustment.

How do I set the time precisely?

Pull the crown to position 2 (the movement stops). For second accuracy, stop the movement when the seconds hand is at 60. Advance the minute hand a few minutes past the target time, then slightly set it back exactly to the desired mark. Push the crown back to position 0 to restart. Tip: for PM setting, ensure you pass noon if needed.

How do I care for my watch?

Clean the case and bracelet with a soft dry cloth. Avoid any contact with chemical or abrasive products. For mechanical maintenance, a complete overhaul is recommended every 5 years by an authorized IWC dealer.

When should the watch be serviced?

IWC recommends an overhaul every 5 years to maintain accuracy and longevity. Additionally, a water resistance check is advised every year, as well as after each opening or service.

What does the rattrapante hand mean?

The rattrapante seconds hand is a chronograph function that allows measuring intermediate times or a second final time. It overlays the chronograph sweep hand and can be stopped independently via the rattrapante pusher without interrupting the ongoing timing.

How do I change the date after a 30-day month?

If the previous month has fewer than 31 days, you must manually advance the date to the 1st of the following month. To do so, unscrew the crown and pull it to position 1, then turn it to the right until the correct date. Avoid doing this between 8 PM and 2 AM to prevent damage to the mechanism.

USER MANUAL Ingenieur Double Chronograph Titanium 3865 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 INGENIEUR DOUBLE CHRONOGRAPH TITANIUM

Your IWC watch shows you the time in hours, minutes and seconds, together with the date and the day. You can use the integrated double chronograph to measure any period of time up to 12 hours in seconds, minutes and hours using the split-seconds hand (rattrapante) to record intermediate times or a second finish time. Stop times can be added together. The mechanical movement with automatic winding has a power reserve of approximately 44 hours when fully wound. Your Ingenieur Double Chronograph Titanium is protected by a sapphire glass of hardness grade 9 on Mohs' scale. Your watch is water-resistant 12 bar. To ensure that this extraordinary watch continues to perform faultlessly in the future, it is essential to observe a few important operating instructions.

THE FUNCTIONS OF THE CROWN

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 (direct 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.

READING THE DOUBLE CHRONOGRAPH

Chronograph seconds hand and split-seconds hand: The scale for the central chronograph seconds hand and the central split-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 1/2-hour display with a continuous hand is situated on the subdial at 6 o'clock.

USING THE DOUBLE CHRONOGRAPH

Start: To start the chronograph, press the start/stop button.

Intermediate timing: Actuate the split-seconds-hand button; this will stop the split-seconds hand, but it will not influence time measurement. You have now recorded an intermediate time while the standard stopwatch continues to run. By actuating the split-seconds-hand button once again, you can cause the split-seconds hand to catch up with the chronograph seconds hand again, and your chronograph is then ready for the next intermediate time stop.

Stop: To stop the chronograph, press the start/stop button again. The chronograph seconds hand and the split-seconds hand stop simultaneously.

Reset: Press the reset button. This will reset all the chronograph hands to zero. The separately stopped split-seconds hand is not automatically reset, but must be reset by pressing the split-seconds-hand button again.

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

Suggestion: In order to avoid placing unnecessary strain on the movement, the split-seconds hand should not be left in a stopped position for long periods. It is essentially only used for the measurement of intermediate times or for recording a second finish time, and should be resynchronized with the chronograph seconds hand once again after doing so.

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.

SERVICING YOUR INGENIEUR DOUBLE CHRONOGRAPH TITANIUM

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 December 2012.
