“Les Nostalgiques” de Numa Jeannin

European Watch Clock and Jewellery Fair 1988 BF 308
The original design of these so-called “coin” watches, with fluted case middle, goes back to the 1925-1930 period. Today, they come with extra-thin quartz movements featuring either a large moon-phase indicator or a double circular calendar for day and date plus a moon-phase indicator. 10-micron goidpiated, water-resistant case.
