The Valjoux 23C is a “triple date” hand-winding chronograph movement in the Valjoux 72 family.
Cal. 23C was introduced as early as 1916 and produced through 1974. Versions before 1938 had a single chronograph pusher (“monopusher”) but Willy Breitling’s dual-pusher concept was added after this.
The Valjoux 23C and 72C are almost identical except that the latter adds a 12 hour counter at 6:00 on the dial.
