A rattrapante chronograph is also sometimes called a split-seconds chronograph. A traditional rattrapante chronograph has two superimposed chronograph seconds hands, which look like a single hand until the split function is used. When you start the chronograph, the two hands run together until you push the split button. At that point, one of the two hands stops, while the other keeps running. Push the split button again, and the stopped hand jumps forward, and the two hands begin to run together again. One common use for the rattrapante is the recording of successive lap times. A triple rattrapante, which allows you to “split” hours and minutes, as well as seconds, has never been done before even though it’s a logical extension of functionality, because even a conventional rattrapante is quite difficult to make and adjust. Like the Double Split, the Triple Split is also a flyback chronograph as well.
