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
1
/
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.
