BREITLING Navitimer B01 Chronograph 43mm Watch Instruction Manual
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
USING THE CHRONOGRAPH
I. MEASURING A SINGLE SHORT TIME
II. MEASURING AN INTERRUPTED SHORT TIME
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 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: 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 sophisticated case fitted
with water-resistant gaskets. Under the influence of certain external factors
such as perspiration, chlorinated or salt water, cosmetics, perfumes or dust,
these gaskets progressively deteriorate. That is why water resistance cannot
be permanently guaranteed, and the gaskets must be periodically replaced,
ideally every two years. We recommend having an annual water-resistance check
conducted. This operation, which takes only a few minutes, may be conducted by
a Breitling authorized maintenance centre, or by an authorized dealer
(www.breitling.com).
The complex construction of the case used for Navi timer models, featuring a design faithful to the vintage 1950s model, means that they are not suited to aquatic activities. The crown, push pieces and bezel must under no circumstances be operated when the watch is wet. The water resistance indication, expressed in bars, must primarily be considered a safety factor, protecting your chronometer from dust and splashing. Only watches that are water-resistant to 5 bars or more should be subjected to repeated immersions.
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 refined materials
and represent extremely high-quality products. Like all objects in natural
hide (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.
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.
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.
