What I know is that the movement is a cal 20F from the 1930's produced in some 48.000 pieces. The cosmetic condition is very very good for its age I think. I'm not sure about the dial. It seems to be a redial ( or rather a new one made ). At least I haven't seen a 20F with a dial even remotely similar to this one. Dial feet at the correct place but that could've been done by a decent watchmaker... ( The golden colored hands look factory made and a perfect fit for the movement, those look genuine to me. ) The same goes for the staybrite steel case. I usually see thick square lugs on the cases housing a 20F, not wire lugs like the ones present on this one. What's your opinion on the dial and case? Does it have any value like that? It runs fine. Thank you !
