Needs research

Method

Reading the number, step by step

  1. 1. Find the movement number

    Swiss case and movement numbers are usually separate sequences by different makers; only the movement serial, where one exists, is relevant to movement dating.

  2. 2. Understand what it encodes

    Numbers on Gallet movements and cases do not form a single published chronological sequence; dating is by calibre, style and documented model references.

  3. 3. Judge how precise the date can be

    Limited: specialist literature covers some lines (chronographs, railway and military pieces) better than general production.

  4. 4. Check the records behind the tables

    Surviving records are fragmentary; the firm's long history and multiple markets make numbering practice inconsistent across periods.
