YOUR BREITLING CHRONOMETER

A chronometer is a high-precision instrument that has successfully passed the entire battery of tests imposed by COSC (Swiss Oﬃ cial Chronometer Testing Institute), a neutral and independent body that individually tests each movement according to the prescriptions in force.
The certiﬁ cation 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 diﬀ recent 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 a rate ranging between only -4/+6 seconds.
The term “chronometer” should not be confused with that of “chronograph”, which is a complicated watch ﬁ fitted with an additional mechanism for measurement of the duration of an event. A chronograph is not necessarily chronometer-certiﬁ ed, but all Breitling chronographs bear the much-coveted title of “chronometer”.

PREPARATION FOR USE

WINDING – TIME-SETTING

| 1. Wind the watch through approximately 40 clockwise turns of the crown.
---|---
| 2. Pull the crown out to position 2. Then adjust the hour and minute.
| 3. Push the crown back into position 1.

USING THE CHRONOGRAPH

I. MEASURING A SINGLE SHORT TIME

Your chronograph is equipped with an exclusive seconds indication device. Unlike a conventional chronograph, the secondhand spins around the dial in 30 seconds instead of 60 seconds. This distinctive feature enables fractions of a second (in this case 1 /8 th of a second) to be read oﬀ eﬀ artlessly.

| 1. Press pushpiece A to start the chronograph. Hand 3 shows the measurement in seconds.
---|---
| 2. Stop the measurement by pressing pushpiece A once more. The measurement is made in hours (totalizer 1), minutes (totalizer 2), seconds, and 1 /8 ths of a second (hand 3).
| 3. Return the chronograph to zero by pressing pushpiece B.

II. MEASURING AND INTERRUPTED SHORT TIME

| 1. Press pushpiece A to start the chronograph. Hand 3 shows 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 up several short times.
| 3. The chronograph is reset to zero by pressing pushpiece B, once the ﬁ nal measurement has been stopped.

SPECIAL CHARACTERISTICS

USING THE TACHOMETER

FIXED TACHOMETER
The tachymetric scale makes it possible to determine an average speed calculated based on the time required to cover a fixed distance of 1 kilometer or 1 mile. The point on the scale where the second hand is stopped after the measurement indicates the average speed in km / h (if the distance covered is one kilometer), or in mph (if the distance covered is one mile).

| Example 1: If it takes 20 seconds to cover one kilometer or one mile, the average speed is 180 km / h or 80 mph respectively.
---|---
| Example 2: If it takes 36 seconds to cover one kilometer or one mile, the average speed is 100 km / h or 100 mph respectively.
| N.B. This tachymetric scale, used in conjunction with the 30-seconds chronograph, is especially suited to measuring high speeds ranging between 95 km / h (or mph) and 320 km / h (or mph). Consequently, the observation time is limited to between 11 and 38 seconds.

SPECIAL CHARACTERISTICS

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 is exactly opposite.

MAINTENANCE

Your Breitling chronometer is a sophisticated instrument that 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 ﬁ fitted with gaskets to ensure its water resistance. Under the inﬂ uence of various external agents – perspiration, chlorinated or saltwater, 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, maybe conducted by a Breitling authorized maintenance center, or by an authorized retailer (www.breitling.com).

Breitling models are water-resistant to varying degrees. The extent of the water resistance, expressed in meters (M), is a standard value and does not indicate an absolute immersion depth. The crown and push-pieces must not under any circumstances be operated underwater 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| 10 bar/100 M/330 FT| 50 bar/500 M/1650 FT+
---|---|---|---|---
Splashing| | | |
Shower, swimming, surface water sports| | | | **
Water-skiing, dives, snorkeling| | | **| **
Diving**| | | |

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 push-pieces.

USEFUL TIPS

Breitling genuine leather straps are crafted with the most reﬁ ned 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 aging 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 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 ﬁ tied with a leather strap, the same advice applies, as well as avoiding getting the strap wet.

WHAT TO AVOID

Like any valuable object, 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 ﬁ eds. Moreover, your Breitling chronometer is designed to run smoothly at temperatures ranging between 0°C and 50°C.
