PREPARING THE WATCH FOR USE
WINDING – TIME-SETTING
1. Wind the watch by rotating the crown around 40 times in
a clockwise direction.
2. Pull the crown out to position 2 and move the hands for-
wards and backwards between 8 pm and midnight so as
to set the calendar to the last day before the correct day
(in progress/current).
3. Turn the hands until the appearance of the exact date, which
jumps at midnight
. Then adjust the hours and minutes.
4. Push the crown back to position 1.
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”.
