Start: To start the chronograph, press the start/stop button.
Intermediate timing: Actuate the split­seconds­hand button; this will stop the split­
seconds hand, but it will not influence time measurement. You have now recorded an
intermediate time while the standard stopwatch continues to run. By actuating the
split­seconds­hand button once again, you can cause the split­seconds hand to catch
up with the chronograph seconds hand again, and your chronograph is then ready for
the next intermediate time stop.
Stop: To stop the chronograph, press the start/stop button again. Both seconds
hands stop simultaneously.
Reset: Press the reset button. This will reset all the chronograph hands to zero. The
separately stopped split­seconds hand is not automatically reset, but must be reset
by pressing the split­seconds­hand button again.
Aggregate time recording: You can add stop times together by pressing the start/
stop button again after the first measurement instead of the reset button.
Suggestion: In order to avoid placing unnecessary strain on the movement, the split­
seconds hand should not be left in a stopped position for long periods. It is essentially
only used for the measurement of intermediate times or for recording a second finish
time, and should be resynchronized with the chronograph seconds hand once again
after doing so.
