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 wristwatch chronographs with quartz oscillators consists in observing each movement
for 11 days and 11 nights, in several positions and at 3 different temperatures (8ºC, 23ºC, 38ºC). To earn the
prestigious chronometer label, a movement's performances must meet 7 very strict criteria, including a daily
variation in rate of within ±0.07 seconds, corresponding to an annual precision of ±25 seconds. The variation
in rate of the S Q ™ caliber fitted in your B

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 B
"chronometers".

General handling principle
The different functions are selected by rotating the crown. The latter has two axial positions: neutral (1) and
pulled out (2).
(1)
In the neutral position, rotating the crown enables you to move from one function to another. The crown may
be turned forwards (clockwise) or backwards (anti-clockwise).
A brief push on the crown lights up the two digital displays for around 6 seconds. The seconds hand then stops
momentarily as an energy-saving measure.
N.B. The type of display used is compatible with night vision goggles.
