Valjoux Cal. 6 is a pocket watch column wheel chronograph movement. Introduced around 1910, it was produced at least through the 1920s. It featured a six-column wheel to control the chronograph function. The chronograph used a central seconds hand with a 30 minute counter. It was a single-pusher design.
