Timing a single event is straightforward; separating two events that unfold together demands far greater mechanical control. The split-second chronograph, known as a rattrapante, is built for this purpose. Two central chronograph hands begin in perfect alignment, then one can be halted to capture an intermediate result while the other continues its course. With a single command, the stopped hand rejoins instantly, restoring synchronized motion without interrupting the ongoing measurement.

Such precision is achieved through a highly sophisticated system within the movement. Clamps, isolators, and additional wheel trains must engage and release with exact timing, ensuring that neither accuracy nor amplitude is compromised. This level of coordination places the split–second chronograph among the most demanding complications in haute horology, where mechanical discipline and engineering mastery operate in complete balance.
