====== Valjoux 23 ======
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.
