Valjoux 22

The Valjoux 22 and similar Valjoux 71 are chronograph movements produced by Valjoux and later ETA for 60 years, from 1914 through 1974.

The Valjoux 22 family was originally designed for pocket watches and is thus a larger movement than is typical for those years, measuring 14 ligne or 31.3 mm. Like its smaller brother, the Valjoux 23, it is a nine-column column wheel chronograph with subsidiary seconds and a minute counter at 9:00 and 3:00, respectively. Valjoux 71 added an hour counter as well.
