Hello everyone, as you can see this is my first post and I need some expert help.
I recently acquired this watch (three photographs attached), which I really like a lot and have been trying to establish as much information about it, as I can . The watch was sold to me as being "all original except for the replaced crystal". From my research and the numbers on the watch, this is what would appear to me, to be the situation.
Case back: stamped on the outside is 007084 but I do not know how to interpret this. Absence of a letter would indicate it is stainless steel, confirmed by the stamping on the inside of "Acier Inoxydable". It is a 'screw down' type and not a 'snap off'.
Case: diameter is approx. 34mm.would appear to be stainless steel as the caseback. Is this an E159 (waterproof) case but missing a waterproof "O" ring.
Movement: is gilded and stamped with the number 366600, calibre P478, but again I do not know how to interpret this.
Dial: looks original to me, although has some spots and discolouration.
Hands: look original to me, but with some corrosion, however I have seen other cal 478's with a 'sword' style seconds hand as opposed to the 'stick' style on mine, therefore I am not sure if authentic.
Crown: looks original to me, but is it correct for this model.
It is possible to date this watch and confirm if the numbers line up, plus, any comments or views on the statement, it is "all original except for the replaced crystal"?
Any information, help or advice would be gratefully received. I do have more photographs and at higher resolution if required.
