Welcome
Seth Thomas made more pattern variants than any other American factory during their 29-year output of pocket watch production from 1885 to 1914, especially in the 18-size Model 5, where the pattern could change on consecutive movements.
On the Seth Thomas Research website you'll find hundreds of photos detailing all of the known models, patterns, and variants from both the regular production runs as well as the prototypical ones.
This is is the oldest, most accurate, and most comprehensive online resource for vintage Seth Thomas pocket watches, featuring:
- Serial number lookup for model identification and searches for approximate dates
- Over 40 charts for grade identification, SN runs, production totals and percentages
- A separate page for each model to research dates, run totals, and known variants
- An entire section devoted to private labels, sorted by name, dial, SN, and state
- Pages for factory dials, hands, cases, period adverts, catalogs and surviving records
- A section describing the known patents, including links to the US Patent Office

Plagiarism
This website has been plagiarized several times by those too lazy to do their own research, most notably by Nathan Moore, the rich owner of the PW Database. One can't help but notice how the PWBD's totals seem to mirror the totals on this site soon after it's been updated.
Attached are numbers for the Seth Thomas two-tone Grade 36 Model 8 so far according to logged examples, along with Nathan Moore's number, which appear strangely identical. Considering that there are no surviving records, where could have Nathan gotten his totals, if not from this site?
Seth Thomas Research
The total of 33,150 two-tone Grade 36s (pictured here) is a red herring, a deliberately wrong number put there to see if he would "borrow" it.
PW Database
And Nathan Moore did just that, inventing a similar total of 33,300. The real total of two-tone Grade 36s is thousands of numbers away.
