I know of the famed Venus chronograph movements, and I know that the 175 in particular has lived on as the Chinese-made Sea-Gull ST19XX family. However, there is very little, if any, information here and elsewhere on the internet on the history of Venus as a maker of complete watches both in the past and the present.
A few years ago, my father had told me that, sometime during his days as a university student, his father had given him a Venus watch, which seems to have been lost somewhere down the line. After looking around, I found out, via the Watch-Wiki and some searching on the net, that Venus was indeed making, besides movements, complete watches with its own name. I learned, through the article on Watch-Wiki, that the brand was relaunched in 2011, making quartz watches with Ronda movements. I found its current web page, and I saw that they also make automatic watches, powered by the ETA 2824-2 and a bunch of movements named "VS CSD-01", "S-TECH IT15", "S-TECH IT10", and "VS PSR-02"; they both beat at 3Hz, and their power reserve of 36 hours seems to be rather mediocre.
However, other than the jewel count, there's very little information on the "VS" and "S-TECH" movements. There were some pointers online to Val-Swiss (whose website is no longer available) and Valanvron, which seems to be making clones of ETA's own movements. Who owns Venus, the company, nowadays? Who makes its non-ETA movements? What are they like, quality-wise? How come their power reserve is so low, given their low beat rate?
Does anyone here have any information about them?
