Dials

All of the known styles of factory dials are shown on this page, including porcelain, metal, embossed, fancy, and aftermarket, along with their matching part number when applicable. Learn about the small local kiln that made them before it burned, where the dial feet were located, and there's even a section on all of the hand styles.


The Dials Page

Cases

Other than the Centennial Line, which was offered as a complete watch cased by the factory, very few watches bear the square-diamond stamp, which was the trademark of the company. There is also one surviving trade list showing the prices from 1888.


The Cases Page

Records

Most of the known trade catalogs and period advertisements are featured here, as well as the corresponding price lists. There's also a section on the six patents associated with the watch aspect of the company, as well as some of the signage and postcards.


The Records Page

Specifics

Anyone interested in just how these antiques work will enjoy this page because it has everything from gear train speeds and mainspring barrels to the plate finishes and all the different types of regulators. Don't miss the section on the latest discoveries and updates.

Swiss Fakes

Before you get too excited about the "vintage" Seth Thomas pocket watch you just bought on eBay, make sure it's not a battery-powered Swiss reproduction from the 1990s.
