    Hi all,

    Do you happen to know what the markings on the caseback actually mean?

    Lunette is french for bezel and its gold plating is 20 microns thick. Fond is french for caseback and its gold plating is 40 microns thick.

    Also I think that plaqué G (galvanique) is electrical plating, and plaqué L (laminé?) is rolled gold, thicker than electrically plated..

    And the last piece of the puzzle, the stamp. CB in a domed box is the case maker, Centrale Boîtes (Central Watch Case Co, Biel, Switzerland).
