from -The complete price guide to pocket watches.

Curator Response: Thanks for the report. Seth Thomas did not produce movements in a strict sequential order. Rather, they assigned larger blocks for specific models. The estimated date above is derived from careful study of the introduction of certain models, period advertisements, and observations. The dates you reference are simply extrapolated from a linear interpretation of production, which is unreliable.
