opened the case and its a 620R swiss made apparently started around 1945.
The crystal appears to be plastic, case nickel chrome with a few nicks and scratches.
After three days it appears to be keeping fairly good time.
Not sure about the 1470332 6518 engraved on the inside of the case, the numbers are not helping me find any information.
movement picture is a little blurry, and yes I cleaned up the watch with a cotton swab before putting it back together.
