YOUR BREITLING CHRONOMETER
A chronometer is a high-precision instrument that has successfully passed the
entire battery of tests imposed by 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 standard ISO 3159, consists of observing each movement for 15
days and 15 nights, in 5 positions and at 3 different temperatures (8°C, 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 for
measurement of the duration of an event. A chronograph is not necessarily
chronometer-certified, but all Breitling chronographs bear the much-coveted
title of “chronometer”.
PREPARATION FOR USE
WINDING – TIME-SETTING
-
Wind the watch completely in a clockwise direction. Do not force.
-
Pull the crown out to position 2 and adjust the hour and minute.
-
Push the crown back into position 1.
Nota bene : wind the watch completely each day (preferably at the same time). Do not force.
USING THE CHRONOGRAPH
MEASURING A SINGLE SHORT TIME
-
Press pushpiece A to start the chronograph. Hand 2 shows the measurement in seconds.
-
Stop the measurement by pressing pushpiece A once more. The measurement is made in minutes (totalizer 1), seconds and 1 /4 of a second (hand 2).
-
Reset the chronograph to zero by pressing push piece B.
MEASURING AN INTERRUPTED SHORT TIME
-
Press pushpiece A to start the chronograph. Hand 2 shows the measurement in seconds.
-
To interrupt the measurement, press push piece A once more.
To restart the time measurement, press push piece A. This procedure makes it possible to add up several short times. -
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 productivity rate, based on an observation period of less than 60 seconds.
-
Average speed
Using the chronograph to measure the time required to cover a kilometer or a mile. The final position of the second hand indicates the average speed. 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. -
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.
SUN COMPASS
Your Breitling chronometer may be used as a sun compass, thus enabling you to determine North and South. For regions that have instated daylight saving time, subtract one hour when aligning 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
South, 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 North, South being exactly opposite.
MAINTENANCE
Your Breitling chronometer is a sophisticated instrument which is constantly 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 relubrication 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: the frequency of this operation varies according to actual use. Breitling or your authorized retailer will be happy to handle the procedure.
WATER RESISTANCE
The movement of your chronometer is protected by a complex case fitted with gaskets to ensure its water resistance. Under the influence of various external agents – perspiration, chlorinated or salt water, cosmetics, fragrances or dust – these gaskets gradually deteriorate. That is why water resistance cannot be permanently guaranteed. If used intensively in water, we recommend having an annual water resistance check conducted. In any event, such an appraisal must be done every two years. This operation, which takes only a few minutes, may be conducted by a Breitling authorized maintenance centre, or by an authorized retailer (www.breitling.com).
Breitling models are water-resistant to varying degrees. The extent of the water resistance, expressed in metres (M), is a standard value and does not indicate an absolute immersion depth. The crown and pushpieces must not under any circumstances be operated under water or when the watch is wet. The table below indicates the conditions in which your watch may reasonably be used, according to its degree of water resistance:
ACTIVITIES / DEGREE OF WATER RESISTANCE| 3 bar/30 M/100 FT| 5
bar/50 M/165 FT| 10bar/100M/330FT| 50bar/500M/1650FT+

If your watch is equipped with a screw-lock crown, ensure that this is locked before any use in water. This also applies to screw-lock pushpieces.
USEFUL TIPS
Breitling genuine leather straps are crafted with the most refined materials
and represent extremely high-quality products. Like all objects in natural
skin (shoes, gloves, etc.), their length of life varies considerably,
according to the conditions in which they are worn. ln particular, water,
cosmetics and perspiration accelerate the ageing process. A metal or synthetic
Breitling bracelet is thus better suited to activities involving frequent
contact with water or moisture.
Breitling metal cases and bracelets are made from the fi nest alloys and
guarantee sturdiness and wearer comfort. Regular cleaning by rinsing and
brushing in clean water will keep your watch shiny. This operation is strongly
recommended after each immersion in salty or chlorinated water. For watches
fitted with a leather strap, the same advice applies, as well as avoiding
getting the strap wet.
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.

DATE APERTURE
STEP 1
Check whether the crown should be unscrewed (counterclockwise) before you
carry out the following steps.
STEP 2
Wind the watch with approximately 40 clockwise turns of the crown until you
feel a resistance.
STEP 3
If the watch has no date aperture, pull the crown out to position 2. Set the
hour and minute.
If the watch does have a date aperture, proceed as follows: pull the crown out
to position 2. Turn it clockwise to adjust it to the day before the activation
date. Pull the crown out to position 3. Move the hands forwards until the
correct date appears at midnight. Set the hour and minute hands.
STEP 4
Push the crown back into position 1. If you had to unscrew the crown in step
1, follow this final step:
press the crown gently, turning it clockwise, then wind the watch until you
feel some resistance.
Do not force it!
NOTE : Your Breitling is a hand-wound mechanical watch.
If it reaches the end of its power reserve, it will stop functioning. Remember
to wind it by following steps 1, 2 and 4!
