Quartz chronograph
Operating instructions2
The time, hours, minutes and seconds functions are driven by a
primary motor using traditional quartz watch technology.
The chronograph functions are provided by a combination of quartz
and mechanical technology. The chronograph hand, driven by a sepa-
rate motor, makes 16 jumps per second. Its movement appears con-
tinuous and it can be read off the scale to within 1/10th of a second.
The reset function, like the minute and hour totaliser functions, is car-
ried out mechanically. The return to zero is instantaneous.
In order to reduce energy consumption to a minimum, the chronograph
automatically stops after more than 11 hours of operation.
The crown has 3 positions:
Watch functions:
1. Normal position (wearing position): when the crown is posi-
tioned against the case, the crown ensures that the watch is water-
resistant.
2. Correcting the date: pull the crown out to position 2, turn the
crown forwards until the required date is displayed, then push the
crown back to position 1.
NB: it is impossible to set the date between 8pm and 2am.
3. Time setting: pull the crown out to position 3. The seconds hand
will stop. Turn the crown forwards or backwards. Synchronise the
seconds by pushing the crown back to position 1 to coincide with
a given time signal.
Chronograph functions:
• Pusher A: start – stop, start – stop etc.
Timing to within 1/10th of a second up to 11 hours.
• Pusher B: reset (after stopping).

The hours, minutes, seconds and chronograph functions are driven
by 4 motors using conventional quartz technology.
The crown has 3 positions:
Watch functions:
1. Normal position (wearing position): when the crown is posi-
tioned against the case, the crown guarantees the watch is water-
resistant.
2. Time zone correction or 30 minutes totaliser hand initiali-
sation.
3. Time setting: pull the crown out to position 3. The seconds hand
will stop. Turn the crown forwards or backwards. Synchronise
the seconds by pushing the crown into position 1 to coincide
with a given time signal; resetting the 1/10th of a second and
60 second totalisers.
Chronograph functions:
Allows the time to be read off to
1/10th of a second up to 30 min-
utes in the simple, addition or split
modes (reading split times, interme-
diate times).
Simple timing function (crown in position 1):
• Pusher A: start – stop (read time)
• Pusher B: reset

Note: if the chronograph has stopped after 11 hours in order to
conserve energy, it cannot be reset without pressing pusher A
beforehand.
