Can anyone help me identify my new Longines without the reference number? I was told it is a 1950's era watch. It is approximately 37 mm from my measurement. Any help would be greatly appreciated!

 

It's hard to identify a watch that has a refinished dial.

 

Oh wow is it refinished!? I had no idea. I did not pay much, but I don't think I would've purchased it at all knowing it is refinished. Thanks though.
