Can you give us a MUCH better picture to work with?
I’d hazard a guess it’s connected to the Venus 175.
Venus 150 ?

Ah cool there are a lot of similarities, probably in the Venus family truly 😀
Yeah it’s just a case of finding the same. There always seem to be small variations through the life of even the same calibre reference, so it’s sometimes difficult.
Could also be a Chinese Seagull movement or an older clone of the Venus 175. What watch model is it? That could help.
