What I have worked out so far:
Movement 1480 - 17 jewel
Serial 33****** - 1971
166098: male - self winding centre second - water resistant calendar
Watch came in original box, with original strap and the strap shown in image.
Has inscription engraved on the back stating service at a company from 1947-1972.
First, does it look to be authentic?
Second, what is it roughly worth? (I'm not selling, just want to know how I did haha)
Also, where else could I try for more information about this range of watch?
Thanks!
