Frequently Asked Questions - Aquatimer Chronograph 3795 IWC

How do I wind and set the time on my IWC Aquatimer Chronograph?

To wind the watch, unscrew the crown (turn left) to position 0, then turn it about 20 times clockwise. To set the time, pull the crown to position 2 (it stops the movement). Advance the hands to the desired time, allowing for the date change at midnight. Return the crown to position 0 and screw it back in by pushing and turning right.

How do I use the Flyback chronograph?

The Flyback chronograph allows you to immediately restart a timing without stopping and resetting. While the chronograph is running, press the reset pusher (8) all the way in. The hands return to zero and the timing restarts as soon as you release the pusher.

What do the different crown positions mean?

The screw-in crown has four positions: X (normal position, screwed in for water resistance), 0 (manual winding), 1 (date setting), 2 (time setting). Never operate the crown underwater and always screw it back in after use.

What is the water resistance of the watch and how do I preserve it?

The watch is water-resistant to 30 bar (300 meters). To preserve water resistance, the crown must always be screwed in at position X during normal use. Have the water resistance checked annually by an IWC service center, especially after an opening.

How do I change the strap on the Aquatimer?

The strap is tool-free interchangeable thanks to the patented IWC system. Press the stop lever located under the lugs, tilt the strap inward and slide it upward. To attach, insert the notch into the pin, tilt outward and snap into place. Check the attachment by pulling firmly on both parts of the strap.

How do I set the internal rotating bezel for diving?

Turn the internal rotating bezel counterclockwise to align the triangle with the minute hand at the start time of the dive. The bezel only rotates in one direction for safety. The luminous markings allow you to read elapsed time in the dark.

What should I do if my watch is exposed to a magnetic field?

Strong magnets (neodymium, etc.) can magnetize the movement and affect its accuracy. If you notice a sudden change in precision, contact an authorized IWC dealer for demagnetization. Avoid direct contact with magnets, even for watches with a soft iron case.

How do I clean the watch after a dive in the sea?

Rinse the watch under running fresh water after each dive, especially in seawater, to prevent salt deposits on the case, strap and clasp. Also clean the SafeDive system area by letting water run through the perforations on the left side of the case.

When and how should I service my watch?

A complete overhaul is recommended every 5 years to replace worn parts, re-oil the movement and remove deposits. Entrust it to an authorized IWC dealer or the IWC after-sales service in Schaffhausen. Between overhauls, have the water resistance checked annually.

Why doesn't the minute hand move immediately when setting?

To ensure instant starting of the minute hand, it is recommended to advance the minute hand a few marks beyond the desired time, then slightly back to the exact mark. This eliminates play in the gear train and ensures immediate movement when restarting.

Stand: April 2014.

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 AQUATIMER CHRONOGRAPH

Your IWC watch shows you the time in hours, minutes and seconds, together with the date. You can use the integrated chronograph to measure any period of time in seconds and minutes. Stop times can be added together. The dive time is read off on the internal rotating bezel, which for safety reasons can only be turned anticlockwise. The mechanical movement with automatic winding has a power reserve of approximately 68 hours when fully wound. Your watch is water-resistant 30 bar and protected by a sapphire glass of hardness grade 9 on Mohs' scale. 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 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 into position X and turning it to the right at the same time, it is screwed down firmly again and secured.

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). The crown must not be moved or used for any purpose whatsoever while under water.

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. The crown must always be in position X when you are wearing your watch.

DATE 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 (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.

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.
• 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

The dial, the hour, minute and seconds hands, as well as the markings on the internal rotating bezel of your watch have luminescent elements that allow you to read the time effortlessly even in total darkness. The two luminescent elements at 12 o'clock serve 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 subdial at 12 o'clock has one hand, which runs continuously and shows the elapsed time on a 60-minute scale. The minute counter can be read like a standard analogue time display. In other words, one revolution of the minute counter is equal to 60 minutes.

USING THE CHRONOGRAPH

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

Flyback: You can start recording a new time immediately, even when the chronograph is running. With the chronograph running, simply depress the reset/flyback push-button fully as far as it will go. Both chronograph hands are reset to zero, and a new measurement is started as soon as the push-button is released.

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

Reset: Depress the reset/flyback push-button fully as far as it will go. This will reset both chronograph hands to zero.

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

MARKING THE START OF A DIVE

The triangle on the internal rotating bezel can be aligned with the minute hand by turning the external rotating bezel. The desired point in time (for example the time of entering the water at the start of the dive) can be set in this way. You can read off the elapsed time (for example the duration of the dive) on the internal rotating bezel. For safety reasons, the internal rotating bezel can only be rotated in an anticlockwise direction. The rotating bezel is indexed audibly and perceptibly in one-minute steps, and it is also legible in the dark thanks to the luminescent markings.

If you are planning to use the watch to time dives, you should be a certified open water diver and have the water-resistance of your watch checked regularly by an IWC service centre.

CHANGING BETWEEN DIFFERENT TYPES OF BRACELET OR STRAP

Your Aquatimer Chronograph comes with a patented IWC bracelet quick-change system that enables you to change the bracelet or strap quickly and simply, without the use of tools. To remove the bracelet or strap, use your thumbnail to firmly push the retaining lever (1) located on the

underside of the horns outwards.

Tilt the bracelet or strap inwards (2) and move it upwards away from the case (3).

To attach the bracelet or strap, hook the notch of the horns from above into the spring pin of the case (4).

Now return the bracelet or strap to its original position (5) while simultaneously pressing it down into the horns to snap it into place (6).

Once you have heard and felt that the bracelet or strap has clicked into place, you can be sure that the bracelet or strap is safely secured.

When using the rubber strap, please be aware that the strap with the buckle should be attached to the 12 o'clock position on the case.

After changing the strap, please ensure that it is securely attached by pulling both sides up (7) and down (8) firmly.

INFORMATION ABOUT MAGNETIC FIELDS

As a result of the ever greater prevalence in recent years of very strong magnets made from rare-earth alloys (for example neodymium-iron-boron) – these are found in objects such as loudspeakers, jewellery and fasteners on mobile-phone cases and handbags – mechanical watches are increasingly likely to come into contact with such magnets and be magnetized. This can lead to the watch rate being permanently affected, a problem that can only be resolved by a process of demagnetization carried out by a specialist. We recommend that you keep your watch away from such magnets.

Watches with a soft-iron inner case provide a higher level of protection against magnetic fields and far exceed the requirements of DIN standard 8309. Nevertheless, it is still possible for the watch movement to be magnetized in the close proximity of very strong magnets. We therefore recommend that watches with a soft-iron inner case also be kept away from direct contact with strong magnets.

Should there be a sudden change in the precision of your timepiece, please contact an authorized IWC Official Agent to have your watch checked for magnetism.

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.

CLEANING THE WATCH AFTER DIVING

After diving – and especially after diving in seawater – you should rinse your watch under running tap water. This will prevent salt incrustation on the case, bracelet or strap and clasp or buckle. You should also clean the wet area of the SafeDive system by rinsing water through the holes on the protective bow on the left-hand side of the case.

SERVICING YOUR AQUATIMER CHRONOGRAPH

Although the parts in this watch are all manufactured from top-quality materials, a number of components are subject to nat ural 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.
