In 1816 Louis Moinet built a "compteur de tierces" to follow the stars to a sixtieth of a second: the first known chronograph. Nicolas Rieussec gave it its name in 1821, to time horse races. The split-seconds, which adds a hand to record an intermediate time, appeared in the 19th century and remains one of the most delicate complications to adjust.
Start the chronograph: both hands set off together, one on top of the other. Press the split pusher: one stops to mark the intermediate time while the other carries on. Press again: it catches up with its twin in a single jump. The reset brings everything back to the start.
Ages 14 and up. Contains small parts: not suitable for children under 3, choking hazard.
