    Serial numbers

    This archive holds no verified serial-number table for this maker. Do not date a piece from its serial number alone; use case hallmarks, movement construction, trade directories and documented comparison examples.

    Collecting significance

    Originality of dial, hands, case and movement is the main consideration. Confirm that the movement belongs to the case and that the dial has not been refinished, and record what is verified separately from what is inferred.
