I just bought this as legit but i dont know, it seems it is as A7 from around 1960, checked and it seems the movement could be donbe by bulova, Hamilton or Elgin but nothing else.
Not yet received i am pretty sure the movement is like the third picture (got from an ebay sale)
What makes me thing i legit is the sphere, is doesnt have the H3 or Radiation logo which is ok for a watch before 1970, so far so good.
Any ideas how could be the maker?

Pictures with time, the one i bought.
Pictures with no time and better quality, the ones from the ebay auction.
