Preparation For Use - Breitling PREMIER AUTOMATIC DAY & DATE Manuel D'instructions

YOUR BREITLING CHRONOMETER
A chronometer is a high-precision instrument that has successfully passed the entire
battery of tests imposed by COSC (Swiss O 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 di 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 – DATE ADJUSTMENT – TIME-SETTING
NB : mechanical watches endowed with a date indicator window are equipped
with a complex mechanism that is set into motion between 8 pm and 3 am. It is
therefore vital to avoid adjusting the calendar or moving the time backwards
during this period.
1. To wind the watch, turn the crown (in position 1) clockwise about
40 times.
2. Pull the crown out to position 2. Turn it counter-clockwise to
display the day prior to the correct day.
Then turn it clockwise to display the date prior to the correct
date.
3. Pull the crown out to position 3 and turn the hands forward until
the current date "jumps" into place, at midnight. Then set the
correct time.
4. Push the crown back to position 1.
