Hi! Let me preface that I know absolutely nothing about watches and am so excited this forum exists. I am trying to identify a few women's watches that my grandmother (in her 90s) gave me. She thinks this one belonged to my great grandmother in the USA, but does not know a year or any history on it.
It has "Zenith USA" on the watch band, with what is maybe a serial number? below it. On the case is and another 4 digit number, and there is a small mark that may be a diamond in the upper center. No brand name on the face, I can't find anything on the inside. I can't find a thing about it.
Band says: ZENITH USA ; 12010K[G]FTOPS or maybe 1[/]2010KFTOPS, not sure about the two characters in the brackets.
Back: maybe diamond at the top, #/argent,
Thank you for any leads you can give me!
I did look at a serial number chart to find the year but I'm not even sure which is the serial number.
Thank you again!
