Venus Cal. 140 is a hand-winding chronograph movement. Measuring 13 ligne in diameter, it has an unusual 5-column wheel to control the chronograph function. It began as a monopusher chronograph in 1935 before adding a second pusher later. It lasted in production until around 1949. It was succeeded by the more advanced Venus Cal. 150.
An unusual design, Cal. 140 places the hour and minute hands in a subdial at 12:00, a 30 or 45 minute chronograph register at 6:00, and a central chronograph seconds hand. This produces a notable 6-12 subdial arrangement with the look of a regulator.
