YOUR BREITLING CHRONOMETER

A chronometer is a high-precision instrument that has successfully passed the

entire battery of tests imposed by the COSC (Swiss Official Chronometer

Testing Institute), a neutral and independent body which individually tests

each movement according to the prescriptions in force.

The certification test for wristwatches with sprung balance oscillators,

according to the ISO 3159 norm, consists of observing each movement for

15 days and 15 nights, in 5 positions and at 3 different temperatures (8°, 23°C,

38°C). In order to earn the prestigious chronometer label, a movement’s

performances must meet 7 very strict criteria, including a daily variation in

rate ranging between only –4/+6 seconds.

The term “chronometer” should not be confused with that of “chronograph”,

which is a complicated watch fitted with an additional mechanism enabling

the measurement of the duration of an event. A chronograph is not neces-

sarily chronometer-certified, but all BREITLING chronographs carry the much-

coveted title of “chronometers”.

PREPARING THE WATCH FOR USE

WINDING – DATE ADJUSTMENT – TIME-SETTING

Nota bene: mechanical watches endowed with a date, day,

month or moon-phase indicator are equipped with a complex

mechanism that is set into motion between 8 pm and 3 am. It is

therefore vital to avoid adjusting the calendar or moving the

time backwards during this period.

1. Wind the watch by 40 clockwise turns of the crown.

2. Pull the crown to position 3 to adjust the hour and the

minute, while referring to the 24-hour display to avoid

any confusion such as between 10 am and 10 pm.

3. Place the crown in position 2. Turn it anticlockwise to

show the right month (the month indication changes

with each full rotation of the hand). Then position

the hand on the exact date.

USING THE CHRONOGRAPH

I. MEASURING A SINGLE SHORT TIME

1. Press pushpiece Ato start the chronograph. Hand 3

shows the measurement in seconds.

2. Stop the measurement by pressing pushpiece A once

more. The measurement is done in hours (totalizer 1),

minutes (totalizer 2), seconds and

5ths of a second (hand 3).

3. Return the chronograph to zero by pressing push-

piece B.

4. Set the right day by using a soft point to press the

pushpiece located at 10 o’clock on the side of the case.

5. Push the crown back in to position 1.

II. MEASURING AN INTERRUPTED SHORT TIME

1. Press pushpiece Ato start the chronograph. Hand 3

allows you to follow the measurement in seconds.

2. To interrupt the measurement, press pushpiece A

once more. To restart the time measurement, press

pushpiece A. This procedure makes it possible to

add several short times.

3. The chronograph is reset to zero by pressing push-

piece B, once the final measurement has been stopped.

SPECIAL CHARACTERISTICS

USING THE TACHOMETER

The tachometer is the graduation on the dial or flange of your BREITLING

chronograph enabling you to determine average speeds or hourly produc-

tivity rate, based on an observation period of less than 60 seconds.

1. Average or mean speed

Using the chronograph to measure the time required to cover a kilometre or

a mile. If it takes 20 seconds to cover 1 km or 1 mile, the scale respectively

indicates an average speed of 180 km/h or 180 miles/h.

2. Hourly productivity rate

Measuring the time required to produce 1 unit. If the chronograph is stopped

at 40 seconds, the tachometric scale indicates 90, corresponding to an hourly

productivity rate of 90 units.

22 23

SUN COMPASS

Your BREITLING chronometer may be used as a sun compass, thus enabling

you to determine the Northerly-Southerly direction. For regions that have

instated daylight saving time, subtract one hour when directing the watch.

In the Northern hemisphere

Point the hour hand precisely towards the sun. In relation

to the watch dial, the point located midway between

the current time and 12 o’clock indicates the South, the

North being exactly opposite.

In the Southern hemisphere

Point the hour-marker located at 12 o’clock on the dial

precisely towards the sun. In relation to the watch dial,

the point located midway between the current time and

12 o’clock indicates the North, the South being exactly

opposite.

24H DISPLAY

Your watch is equipped with a 24H or “military” time display. It serves as

a complement to the conventional display of hours, minutes and seconds.

Directly driven by the timekeeping mechanism, it also serves as an AM/PM

indicator when setting the time on the watch.

MAINTENANCE

Your BREITLING chronometer is a sophisticated instrument which is con-

stantly subjected to a wide variety of stresses and strains. Within a very

small volume, a large number of components contribute to handling all the

functions. Their mechanical action inevitably leads to a certain amount of

wear and tear, which may be controlled by maintenance consisting of renew-

ing the lubrication and replacing worn components. Like any precision

measurement instrument, your watch must be regularly maintained in

order to function at its highest level of potential: we recommend a regular

service every two years, while the complete overhaul should be scheduled

about every five years. Your authorized BREITLING dealer will be pleased to

handle this for you.

WATER-RESISTANCE

The movement of your chronometer is protected by a sophisticated case fitted

with water-resistance gaskets. Under the influence of certain external factors

such as perspiration, cosmetics, perfumes or dust, these gaskets progressively

deteriorate and must be periodically replaced, ideally every two years.

Moreover, we recommend an annual water-resistance test, which takes only

a few minutes, performed by your authorized BREITLING agent.

1/100th OF AN HOUR DIAL DISPLAY

Your BREITLING chronometer is equipped with a scale dividing the hour into

hundredths, thus making it easier to read off the minutes on a decimal base.

E.g.: 0.6h = 36minutes.

WHAT TO AVOID

Like any valuable objects, BREITLING chronometers deserve special care. It

is important to protect them from jarring and knocks by hard objects, and

not to expose them to chemical products, solvents, dangerous gases, or

magnetic fields. Moreover, your BREITLING chronometer is designed to run

smoothly at temperatures ranging between 0°C and 50°C.

The complex construction of the case used for NAVITIMER models, featuring

a design faithful to the vintage 1950s models, means they are not suited to

aquatic activities. The crown, pushpieces and bezel must under no circum-

stances be activated when the watch is damp. The water-resistance indica-

tion, expressed in bars, must be considered a safety factor, protecting your

chronometer from dust and splashing. Only watches that are water-resis-

tant to 5 or more bars should be subjected to repeated immersions.

USEFUL TIPS

BREITLING genuine leather straps are crafted with the most refined materi-

als and represent extremely high-quality products. Like all objects in natu-

ral skin (shoes, gloves, etc.), their length of life varies considerably, accord-

ing to the conditions in which they are worn. In particular, water, cosmet-

ics and perspiration accelerate the aging process.

BREITLING metal cases and bracelets are crafted from the finest alloys and

ensure sturdiness and wearer comfort. Regular cleaning with a soft damp

brush will keep your watch shiny. For watches fitted with a leather strap,

proceed in the same manner, taking care to avoid wetting the strap.
