I just acquired this small ebauche movement watch that is marked "Remontoir-Cylindre 10 Rubis" I am attaching a picture of the Hallmarks inside the back cover and would like to know if they indicate a country of origin and any other factors regarding the watch. I know what the Argent 800 signifies....Thanks.........Keith

The crown & cresent is a silver hallmark from Germany. Argent is French for silver, the "800" oval appears to be a silver content mark. The winged mark is more likely a trade mark for a watchmaker.

Best regards,
