after visiting your forum the past few months and learning a lot about vintage watches I am hoping someone can help me with the following. I recently purchased a rather sorry looking Oris. The case is gold plated with stainless steel back, inside the back cover there are no makers marks. The back is stamped with the usual - Top gold plated G
Stainless steel back, shock resistant, Oris watch co swiss. However when I removed the strap there was another marking on the upper gold plated portion of the case - underscored 8 with a shield next to it with FF and an M underneath.
I have searched the internet but cannot find anything other than a inverted triangle with FM and an F underneath for the Montilier Watch Co. Are they two versions for the same company ? I have tried to take a photograph, however cannot get a clear picture and do not trust my artistic skills.
Thanks for looking and any help / assistance or advice would be appreciated.
