REMONTAGE-MISEA L'HEURE

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^, 38^) . 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 necessarily chronometer-certified, but all Brell Ling chronographs carry the much-coveted title of "chronometers".

PREPARING THE WATCH FOR USE

WINDING-TIME-SETTING

Note biomechanical 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.

1. Pull the crown out to positio n 2, turn it clockwise to adjust the calendar to the day prior to the date when it is set into operation.

1. Pull the crown out to position 3. turn the hands so as to make the calendar jump once when the hands pass through midnight. then adjust the hour and minute.

1. Push the crown back in to position 1.

USING THE CHRONOGRAPH

I. MEASURING A SINGLE SHORT TIME

1. Press pushpiece A to start the chronograph. Hand 3 shows the measurement in seconds.

1. Stop the measurement by pressing pushpiece A once more, t he measurement is done in hours (totalizer 1), minutes (totalizer 2), seconds and 1/4ths of a second (hand 3).

1. rcturn the chronograph to zero by pressing pushpiece B.

H. MEASURING AN INTERRUPITED SHORT TIME

1. Press pushpiece A to 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. t his procedure makes it possible to add several short times.

3. t he chronograph is reset to zero by pressing pushpiece B, once the final measurement has been stopped.

SPECIAL CHARACTERISTICS

SECOND TIMEZONE

the second, independent hour hand (A) makes a complete sweep of the dial in 24 hours. Its position relative to the 24-hour markings inscribed on the dial rim can serve as a second timezone indication. The hand is reset by pulling the crown out of position 2 and rotating it counterclockwise.

SUN COMPASS

Your Breil Ling chronometer may be used as a sun compass, thus enabling you to determine the n orthorly-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 n orth 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 n orth, the South being exactly opposite.

MAINTENANCE

Your Breltling 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 renewing 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 Breltling 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 B re lt Ling agent.

t he complex construction of the case used for n AVItIImer models, featuring a design faithful to the vintage 1950s models, means they are not suited to aquatic activities. t the crown, pushpieces and bezel must under no circumstances be activated when the watch is damp. t the water-resistance indication, expressed in bars, must be considered a safety factor, protecting your chronometer from dust and splashing. Only watches that are water-resistant to 5 or more bars should be subjected to repeated immersions.

USEFUL TIPS

Bret Ling 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. In particular, water, cosmetics and perspiration acelerate the aging process.

Brett Ling metal cases and bracelets are crafted from the finest alloys and ensure sturdyness 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.

WHAT TO AVOID

Like any valuable objects, B reIt Ing 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 B reIt Ing chronometer is designed to run smoothly at temperatures ranging between 0^ and 50^ .
