Seth Thomas Research

Welcome

The Seth Thomas Research website is the most accurate and comprehensive online resource for the factory's 29-year output of pocket watch production from 1885 to 1914, featuring:

Serial number lookup and search returns for date, model, grade, and jewel count
Over 40 charts for serial number blocks and production totals and percentages
A separate page for each model to explore 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
A Store for replacement parts by model, complete with the original factory number

Data Submissions

Photographs of new examples are always needed.

If you have any watches or paper records in your collection then please share them with us.

Catalog prints and period ads will be posted to the Records page, and your watch will be logged on the appropriate chart, adding to the totals and making the search functions more accurate.

Pocket watch dial and movement photos only, please.

The PW Database

Collating millions of extant pocket watch examples would be an enormous task, so the ability for collectors to upload their own pieces became a central feature of the huge PWDB website in order to allow the site to auto-populate and to give the contributors a sense of community. The glaring flaw in that approach is that if an uploaded watch is misclassified, then there is no one to correct it, and anyone doing future research assumes it to be valid even if it's clearly wrong. Once enough people believe a thing to be true it becomes the accepted definition, and certainly no one is going to argue if the Database tells them their watch is rare or a higher grade than it actually is.

To test this theory, site owner Nathan Moore decided to invent a Grade 182 "Special" in common 17-jewel lever-set Model 5 Seth Thomas watches, starting somewhere in 2022. This grade does not exist anywhere - in any of the surviving catalogs, period literature or advertisements.

Until roughly January of 2023, the PWDB had no information about Seth Thomas run totals and grade production, which made sense given the lack of information on his site, so Nathan simply made the numbers up out of thin air. He could have written the .html site code to return the word "Unknown" when there were gaps in the data, but he deliberately chose not to.

The 17-jewel Grade 506 in the Model 3 (pictured) is a perfect example. Despite having logged only three of them by late 2023, the Database stated that there were five runs with a ridiculous overall total of 1,600 for this second-highest grade that spanned around only four years, but so far the data shows at least nine small runs with a combined total of fewer than 300. The total production of the Model 3 in all grades was a little under 40,000 and nearly half of them was the gilt 7-jewel Grade 33, so there's no way 1,600 of the remaining 20,000 was the Grade 506.

Consider why the Database exists in the first place. Google and eBay ads may not pay enough to justify all the work. Altruism is certainly a possibility, but the cost to buy servers, pay people to write a staggering amount of code to support the site, catalog thousands of documents, pore over hundreds of period ads for photos, and constantly update it would be considerable. Nathan has awarded himself seven different badges on his own site, including Founder and Expert, which is interesting since it allows small changes to be made in the lexicon, likely to see if the masses will blindly follow. And they did, pasting it straight into their eBay listings without question.

Jonathon Luysterborghs, special research assistant to the Database, adroit at 7-jewel variants and renowned Seth Thomas Expert, has been known to plagiarize this site and the Ehrhardt volumes, posting the data into various online groups as his own work. He excels at collecting ruined examples, installing the wrong dial and hands, stuffing them into junk nickel cases, and uploading such messes to the PWDB so they can forever be regarded as quality pieces. Well done.
