What is Split-second Chronograph?

It is used to measure the time of different events that begin but do not end together. Activating chronograph, two hands continue to move simultaneously, press the push-button to stop the first hand when the first event ends, after reading the intermediate time a second push on the button makes it catch up with the first ­hand and the two continue their movement together. At the end of the second event, the split-seconds hand is stopped again to read this second intermediate time, and so on. At the end of the last observed event, both hands can be stopped and returned to zero.
