Setting instructions
Winding and time setting:
The winding and time-setting crown (I) can be placed in two
positions A and B.
A: Pushed down against the case, winding position.
This is the normal position when the watch is being worn and
guarantees the best water-resistance.
When the power-reserve hand (4) is close to the minimum, or
every day at roughly the same time, wind the watch by rotating the
winding and time-setting crown (I). The power-reserve hand (4) lets
you monitor how much the watch has been wound.
Do not force the winding mechanism when you feel resistance
increasing.
When the power reserve hand (4) is on the minimum graduation, the
spring is almost entirely unwound and the watch may stop or be less
accurate.
B: Time setting position.
When pulled out to this position, rotation of the winding and time-
setting crown (I) enables the time to be set. Afterwards push the
winding and time-setting crown (I) back to position A to restart the
watch.
It is generally preferable to set the time by advancing the hour and
minute hands (1 and 2) in the clockwise direction. The hands can
however be moved backwards provided you end the adjustment by
advancing them.

Chronograph functions
The timing function can only be used with the winding and time-
setting crown (I) in position A.
1
press on pushpiece (II):
st
Start the chronograph seconds hand (5) and the chronograph
minute hand (6).
2
press on pushpiece (II):
nd
Stop timing.
3
press on pushpiece (II):
rd
Reset the chronograph hands (5 and 6).
Reading the pulsimeter scale (7)
After measuring the time elapsed on completion of 30 pulses, this
scale lets you read the frequency in pulses per minute directly
opposite the chronograph seconds hand (5). Intended originally for
counting the beats of the heart ("Medicus" watches), this scale can
also measure the frequency of any regular movement occurring at
a rate of between 40 and 200 cycles per minute.
Water-resistance
The water-resistance of the watch has been tested at a pressure
of 3 bar.
