Method

Reading the number, step by step

  1. 1. Find the movement number

    Cases, including cast figural cases, were made in quantity and catalogue names identify models; movements were sometimes replaced in service.

  2. 2. Understand what it encodes

    Ansonia clock movements generally do not carry individual production serials usable for dating.

  3. 3. Judge how precise the date can be

    Needs research: date by model name in reprinted catalogues and by trademark form; give a range, not a year.

  4. 4. Check the records behind the tables

    No surviving complete serial ledger is publicly known; dating relies on catalogue reprints, trademarks and case styles.
