Self-winding split-seconds chronograph
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-
ê
graph totalisers for hours (G), minutes (E) and seconds (F) continue
to measure the elapsed time.
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
ê
chronograph seconds hand (F) as explained in step 3 before the
chronograph mechanism is reset/zeroed.
