Preparing The Watch For Use - Breitling COLT CHRONOGRAPH II Bedienungsanleitung

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 (8°C, 23°C, 38°C). 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
UPer Uartz
exceeds these demands, achieving a rate of ±15 seconds a year.
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 B
coveted title of "chronometers".
