Valjoux Cal. 61 VBB is a pocket watch column wheel chronograph movement. Introduced around 1932, it was produced through the 1963. It featured a six-column wheel to control the chronograph function. The chronograph used a central seconds hand with a 30 minute counter.
This was a mono-pusher design, with the chronograph controlled by a pushbutton located coaxially inside the crown. This single button starts, stops, and resets the chronograph timer in order.
This is a “lépine” pocketwatch movement, with the small seconds placed on the same axis as the winding crown. In a pocketwatch, this would place the small seconds at 6:00 with the winding crown at 12:00. The image above would show its placement in a wristwatch, with the winding crown at 3:00 and the small seconds at 9:00.
