This unusual split-seconds chronograph is activated via the crown.
The action is as follows:
- first depression splits the hands and stops the lower chronograph hand; the upper chronograph seconds hand continues to run
- second depression stops the second chronograph hand
- third depression rejoins the two chronograph hands and they simultaneously start running again
