The Valjoux 92 was a popular chronograph movement from the 1950's.
Succeeding the popular Valjoux 23 family (including the Valjoux 72), the Valjoux 92 was similarly sized at 13 ligne (29.5 mm) but used very different technology. It was an oscillating pinion design, distinct at a glance for having two rather than three chronograph engagement wheels visible at the back. Although both Valjoux movements are column wheel designs, the Valjoux 92 has seven pillars versus the nine of all other Valjoux movements.
