Of all the different text found on the plates of Seth Thomas watches, it appears that only four of them were generated in-house, which are known as named grades. This was not new; other firms chose to name some of their watches after their presidents, like Elgin's BW Raymond or Illinois's Bunn Special, and factory workers or superintendents like PS Bartlett, who worked for Waltham. The Seth Thomas named grades are Centennial, Century, Henry Molineux and Maiden Lane.





Contract grades are like private labels in that someone paid the factory to put specific words on a watch, but while private labels are either names of individuals or a small group, contract grades were made for larger concerns like retailers and wholesalers. The origins for some of these grades have been established, but many others will probably never be known, like Adonis, Bismarck, Criterion, Providence, Sentinel, Toronado, and the Model 12 Athabasca, pictured here. Guesses can be made, of course, given the matching 24-hour Canadian dial as a clue, that it perhaps had something to do with the Athabasca oil sands in Alberta, Canada, but without a paper trail who really knows?
The origins of some of Seth Thomas's contract grades were already known, such as the Edgemere being produced for Sears Roebuck & Co, or the Montgomery Ward, which wasn't too hard to figure out, but researching these sources is getting easier, thanks to old publications constantly being digitized and made public. Here are some of the known retailers behind the contract names:
