The ultimate chronograph
The development of a triple rattrapante mechanism that controls three hand pairs collectively or separately confronted the engineers with enormous technical challenges. Even a simple rattrapante mechanism has two hands attached to arbors that run one inside the other. In the case of the triple rattrapante mechanism, this arrangement is three-fold: two seconds hands as well as two hands each for the minute counter and the hour counter. For the watchmakers, the multiple arbor configurations require the ultimate in dexterity and extreme patience in adjusting the endshakes.
