Historical and Technical Significance:
The Venus 170 set a precedent for future Venus calibers such as the 150 and 175, combining quality and cost-effectiveness. Its use of an oscillating pinion, unlike traditional horizontal clutches found in many contemporaries, facilitated efficient chronograph engagement. The movement also employed a rocker bar to select crown functions and uniquely positioned the winding click on the dial side. Despite being less popular in later decades due to its unusual dial layout, the Venus 170 played a significant role in mid-20th century watchmaking, offering a reliable and cost-efficient chronograph solution widely used in the 1940s.
Overall, the Venus 170 remains a respected vintage chronograph movement known for its sturdy build, economic design, and distinctive functionality, making it a fascinating subject for collectors and horologists alike.
