I've been looking the years of production of this watch, it sais 100 fathoms, I think it was to "compite" with the Blancpain 50 fathoms.
and more, in the back has 100/81 10aSN what those numbers an letters mean?
The watch its beautyful, I relumed hands and indicators but did not touch the dial, and had to chanche the crown that was a bronze decolorated one not personalized to a new Enicar crown (push-pull, as the original).
Added new gasquets on,
so I can shawer with it.
I apreciatte your answers and comments.
