Three Stars Watch

This is the watch I acquired in 2014 after my old Molnija's mainspring broke and my local repairman couldn't find a replacement part. The pictures were taken by whoever sold it to me on Yahoo Auctions. I've never been able to find anything about the brand unfortunately, though supposedly it's Swiss and from the 1930s.

If you know anything about the maker, please do contact me. Ψ
