Venus Cal. 178 is part of the Venus 175 family of movements. It is a hand-winding column wheel chronograph movement. Similar to the base Venus 175/176, it adds a 12-hour chronograph register at 6:00. The dial features a 3-6-9 subdial arrangement. The hour counter was still fairly uncommon at this time, and the three-subdial arrangement remains very attractive.
Cal. 178 was introduced around 1947, substantially modified in 1949, and retired around 1960.
