That one has a Soviet-built Poljot 2414 movement (apart from the ratchet wheel replaced). However the case does not look a Soviet design. From that I woud assume that the movement was probably cased-up in the USA, which would have been the intended market according to the Mikrolisk info. The style of the dial is early/mid 1960s, when some Soviet movements were being used in watches sold in the USA (obviously with their origins well disguised).I know nothing about the brand, but from this one that's available on eBay (Vintage Henri Gireaux 17 jewel Man's gents wrist watch with band | eBay) that shows a non-signed movement, it makes me wonder if it was the name of a jewelry store that sold their own brand of watches. Just a thought.
