Hi Brian,
Unfortunately, I know very little about it's provenance. I bought it from a woman whose parents lived for a long time in France (as she did as a child) so my initial impression is that it may have been purchased there. That is only a guess, though. If it was purchased in France, I wonder why the back would be marked in English (25 ATMOS & 800 FEET SWISS MADE-STEEL). The only mark on the movement is MG 232 (I'm not certain as to the last number as it is obscured by one of the spinning wheels). The large self-winding plate and most of the movement is gold colored. It was either cleaned or adjusted in 1978, as the repairman's mark is on the inside of the back. I had a question about potential value as I don't want my wife to wear it daily without having some idea of worth. I understand this forum is not a place to discuss that but if there is a forum or website that is appropriate, please let me know. Thanks very much for your response.
Gerry
