PREPARING THE WATCH FOR USE

WINDING – TIME-SETTING
Nota bene: mechanical watches endowed with a date, day,
month or moon-phase indicator 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. Unscrew the water-resistant crown in an anti-clock-
wise direction. Wind the watch by 40 clockwise turns
of the crown.
2. Pull the crown out to position 2, turn it anti-clock-
wise to adjust the calendar to the day prior to the
date when it is set into operation.
3. Pull the crown out to position 3. turn the hands so
as to make the calendar jump once when the hands
pass through midnight. then adjust the hour and
minute.
4. Push the crown back to position 1. Press it gently,
turning it gently in a clockwise direction, then tigh-
ten it again until you feel some resistance. Do not
force!

USING THE CHRONOGRAPH

I. M
EASURING A SINGLE SHORT TIME
Your chronograph is equipped with an exclusive seconds indication device.
Contrary to a conventional chronograph, the seconds hand spins round the
dial in 30 seconds instead of 60. this distinctive feature enables fractions of a
second (in this case 1/8 of a second) to be read off effortlessly.
1. Press pushpiece A to start the chronograph. Hand 3
shows the measurement in seconds.
2. Stop the measurement by pressing pushpiece A once
more. the measurement is done in hours (totalizer 1),
minutes (totalizer
2),
1/8 of a second (hand 3).
3. return the chronograph to zero by pressing push-
piece B.
