The Venus 188 is a renowned manual-wind chronograph movement introduced in 1948, notable for its cam-switching mechanism which made it a more affordable alternative to column wheel chronographs. It features 17 jewels, a 45-hour power reserve, and operates at 18,000 vibrations per hour. Its layout includes a small seconds subdial and a 30/45-minute totalizer, making it a versatile and reliable choice in vintage chronographs.
Key points about the Venus 188 watch movement:
Introduced in 1948, the Venus 188 was part of a family of cam-switching chronograph movements that included models 180, 190, and 200.
It had a significant impact on chronograph design by providing a cost-effective solution compared to traditional column wheel movements.
The movement has a 17-jewel configuration and a manual winding system.
Power reserve of approximately 45 hours.
Operates at 18,000 vibrations per hour (vph).
The dial layout includes a small seconds subdial at 9 o’clock and a 30-minute or 45-minute totalizer at 3 o’clock.
Cam switching is used for the chronograph function, distinct from column wheel designs.
In 1966, after Venus was acquired by Valjoux, the Venus 188 was modified into the Valjoux 7730.
This modified design later evolved into the Valjoux 7733 and eventually the famous Valjoux 7750, one of the most widely used automatic chronograph movements in the world.
The Venus 188 and its successors are highly regarded and sought after by watch collectors and enthusiasts for their historical importance and reliable engineering.
The Venus 188 remains a benchmark in vintage chronograph movements, representing both innovation and affordability in mid-20th century mechanical watchmaking.
