Seth Thomas Research

Welcome

The Seth Thomas Research website was created to reconstruct the factory's 30-year output of pocket watch production and exists as a gathering point for data. It's the most accurate and comprehensive online resource for vintage Seth Thomas pocket watches, featuring:

Serial number look-ups and search functions for model, grade, and jewel count
Over 40 charts for logged examples, serial number blocks, and named grades
A separate page for each model, exploring dates, run totals, and known variants
An entire section devoted to private labels, sorted by name, dial, SN, and state
Pages for factory dials, cases, period adverts, catalogs and surviving records
A section describing the known patents, including links to the US Patent Office

Photo/Data Submissions

Pictures of new examples are always appreciated.

If you have any examples in your collection or have paper records then please share them with us. Your watch will be categorized based on model, grade, finish and jewel count, and logged on the appropriate chart, adding to the totals and making the search functions more accurate.
