Self-winding split-seconds chronograph
Operating instructions
2
Chronograph functions:
•
Pusher A:
start - stop, start - stop, etc.
Timing to within 1/8th of a second for up to 12 hours.
•
Pusher b:
reset (after a stop).
Note:
never push the chronograph’s two pushers (A and B) simul-
taneously (calibre 3612).
Chronograph functions with split-seconds:
The split-seconds function allows split times to be recorded whilst
the chronograph is running.
1. Start the chronograph by pressing pusher A (start).
2. To record a split time, press pusher C. The split-seconds hand D
stops, indicating the split time, whilst the chronograph continues
running.
Nb:
the split time should be read immediately, since the chrono-
graph totalisers for hours G, minutes E and seconds F continue
to measure the elapsed time.
For calibre 3600 only:
whilst the chronograph is running, do
not leave the split-seconds hand D stopped any longer than is
necessary to read the split time, otherwise the functioning of the
split-seconds mechanism may be affected.
3. Press pusher C for the split-seconds hand to catch up with the
chronograph seconds hand F.
4. To record a new split time, start from step 2 above.
5. Press pusher A to stop the chronograph.
6. Press pusher B to reset.
Nb:
the split-seconds hand D must have caught up with the
chronograph seconds hand F as explained in step 3 before the
chronograph mechanism is reset/zeroed.
