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.
It will be classified on what it really is and not by projected numbers or wishful thinking, nor will it be "verified" by unknown persons. Please report any errors that you discover.

Seth Thomas made some dazzling pieces, which is what caught my eye, and they produced movements with more pattern variations than any other American brand, which is why I collect them. I discovered just how little information there was after winning my first one at auction in 2005 (see inset photo). Given the near-total lack of a paper trail it seemed the only way to reconstruct the factory's output was to document every movement that I could find.
I started scrolling through past events from online venues, cataloging the photos on my PC, and finding enough adverts in the early jewelers supply houses to assemble a grade chart. I bought reprints of original Seth Thomas catalogs and modern Price Guides. I checked for web scans from period trade magazines and the mail-order giants of the day to expand the list of known named grades, and began tracking private labels. I attended local meets and shows with my camera, pestering friends to take photos for me when I couldn't be there.
I called the Historical Society in the factory hometown of Thomaston, Connecticut and was told that there were no records. The NAWCC was of absolutely no help and their library told me that they had no records either, which was hard to believe. I wrote to the larger NAWCC chapters asking for help and never heard back from any of them. I approached some of their officers and admins several times about a collaborative effort, but they stonewalled me. There are also plenty of private collectors who won't share photos or data either.

After launching the Seth Thomas Research site in 2015, I discovered that the biggest problem is photographs; even with the advent of digital cameras and smartphones, taking a decent picture is apparently difficult for some people. You can't believe how many auction houses simply refuse to open the back of a watch and take a single goddamn picture.
I pay hundreds a year to maintain this website of mine, updating the charts every month and adding to my collection, some of which is visible on these pages. People write me often and I'm willing to share what I know, so my hope is that this site helps you to learn a little more about the history contained in the heirloom that you hold in your hand. - - Eric Unselt

And everyone who sent photos and data!
In 2020 roughly 11,000 people visited the Research site to avail themselves of the charts, data, patents, ads, and hundreds of photos found here and nowhere else.
This website is both maintained and funded privately, which takes time and money.
Please help out if you can.
