YOUR BREITLING CHRONOMETER
A chronometer is a high-precision instrument that has successfully passed the entire
battery of tests imposed by COSC (Swiss Offi cial Chronometer Testing Institute), a neutral
and independent body which individually tests each movement according to the pre-
scriptions in force.
The certifi cation 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 diff erent 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 fi tted with an additional mechanism for measurement of the dura-
tion of an event. A chronograph is not necessarily chronometer-certifi ed, but all Breitling
chronographs bear the much-coveted title of "chronometer".

PREPARATION FOR USE

WINDING – TIME-SETTING
Important:
mechanical watches with a date indicator window are equipped
with a complex mechanism that is triggered between 20:00 and 04:00. It is
therefore vital to avoid adjusting the calendar or setting the time backwards
during this period.
1. Unscrew the water-resistant crown counter-clockwise.
Wind the watch by approximately 40 clockwise turns of the
crown.
2. Pull the crown out to position 2, and then adjust the hour
and minute.
3. Push the crown back into position 1. Press it gently, turning
it gently clockwise, then tighten it again until you feel some
resistance.
Do not force!
