The chronograph mechanism
The chronograph function enables the precise determination of stopped times. Beyond the capabilities of a pure chronograph, a rattrapante, or split-seconds, chronograph can also measure intermediate times and determine minimum and maximum values in the course of a given minute. In addition, a double rattrapante chronograph like the DOUBLE SPLIT has even a pair of rattrapante hands that – during a time measurement – can be independently stopped any number of times while the chronograph hands continue to run.
