I´ve just bought a Marc Nicolet Skindiver (1967) automatic. 30 atm. It has (as far as I know) an ETA 2472. I´ll receive it tomorrow!
Anyway, I´ts been really difficult to find any information about the watch or the brand. Do you know anything? Also, I´ve stumbled upon pictures of a Breitling Oyster Geneve, apparently looking like the exakt same watch except for the naming on the dial (and the fact that it was 20atm). Was there cross-production or the like going on at the time?
here´s the watch!
