to ensure optimum water-resistance. Another benefit of this system: it enables
the push-pieces to be locked in the closed position, thereby preventing any
unintentional operation of the chronograph.
To enable use of the chronograph functions, move the push-pieces into the
“open” position by turning the wing-nuts a quarter-turn downward. The non-
compressed gasket position (“open”) will be indicated by an arrow (front view
of watch).
Timing
- The chronograph is activated by pressing the push-piece at 2 o’clock once.
The central seconds hand will turn, and the minute and hour timing counters
will run. Pressing the push-piece at 2 o’clock again will stop the chronograph,
enabling the timing measurement to be read.
- Reset by pressing the push-piece at 4 o’clock to make another timing meas-
urement.
- It is possible to add together several timing measurements by pressing the
push-piece at 2 o’clock again (without resetting the counters). Timing is re-
started, and is added to the previous measurement.
Once the timing operation is complete, move the push-pieces to the compressed
gasket (“closed”) position by turning the wing-nuts a quarter-turn upward, in the
direction shown by the single arrow.
