DAy/NIGHT INDIcAToR
Introduction
The day/night indicator uses a system of discs representing the sun and moon to indicate whether
it is day or night. The special window depicts the night sky, in which the shape of the moon and
sun changes as the day advances.
Reading
when setting the time, take into account the day/night indication, as this is synchronised with
the hour and minute indications. For example, at midnight, the moon should appear at 6 o’clock,
while at midday the sun should appear at 6 o’clock.

Introduction
The chronograph seconds are displayed by a large center hand. The
minute, and possibly the hour, are generally displayed by 1 or 2 small
counters.
The seconds hand and the counters are interconnected.
On certain models, minute timing may also be indicated by a center hand
pointing to the dial’s graduated rim.
Setting
A.
Press your watch’s push button at 2 o’clock: the center seconds hand
will start.
B.
Press the same push button at 2 o’clock again: the center seconds
hand will stop.
c.
Press your watch’s push-button at 4 o’clock: the center seconds and
the counter hands will return to zero.
Warning:
while the second hand is working, never reset to zero to prevent
damage to the mechanism. Always check the second hand has stopped
before resetting to zero.
