The Cal. 175 family consists of standard and split-seconds column wheel chronograph movements with hand winding. All are 14 ligne (31.0 mm) diameter and between 5.7 and 8.55 mm in height. They operate at 18,000 A/h and have a 7-column wheel to control the chronograph.
All models feature small seconds at 9:00 on the dial. Basic models feature a 3-9 subdial arrangement with a 30-minute chronograph counter at 3:00, while many add a 12-hour chronograph register at 6:00. Complicated calendar models add a date by pointer subdial at 12:00 with moon phase and full calendar optional.
The Cal. 175 family was based on the 13 ligne Cal. 150 family, introduced in 1938.
The Cal. 175 family was introduced in 1942, refreshed in 1949, and retired around 1960. After production ended, Venus sold the design and machinery used to produce the Cal. 175 family to the Tianjin Watch Company in China. This became the basis for the Sea-Gull ST19 watch family, introduced in 1963 and re-introduced for current production today.
