Welcome
The Seth Thomas Research website was created as a gathering point for data, and to reconstruct the factory's 29-year output of pocket watch production from 1885 to 1914. It's the most accurate and comprehensive online resource for vintage Seth Thomas pocket watches, featuring:
- Serial number lookup and search returns for date, 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
Seth Thomas Research is a contributor to the American Horology Archive.
