The Valjoux 23 family of chronograph movements was widely used and produced for nearly 60 years.

The Valjoux 23 family is 13 ligne in size (29.5 mm) with a nine-pillar column wheel. It is typically a two-register design, with small seconds at 9:00 and a 30- or 45-minute counter at 3:00. Flyback, calendar, moon phase, and other complications were sometimes offered as well. The well-known Valjoux 72 was a variant with three subdials, adding an hour counter at 6:00.
