This watch is equipped with two chronograph mechanisms, each working on its own column wheel and therefore having independent functions. Thanks to their respective control buttons, each of them can be activated independently of the other; the two chronographs perform the start/stop/ return to zero functions, and each drives its own 30-minute counter (these are with instantaneous jumps).
