I am grateful to be in a position to share information about important Seth Thomas research reference sources with the visitors to this website.  I am only able to do so after closely studying information presented by Roy Ehrhardt in his numerous volumes of data on all American pocket watches, and studying the information related to Seth Thomas pocket watches as presented on the Pocket Watch Database by its founder Nathan Moore. Gaining a foothold understanding led me to hunt for and studying all of the information from third party sources that I could find.

Research into the Seth Thomas product line depends heavily on period advertising because there are virtually no records available through the manufacturer. The back-to-back hurricanes, Connie and Diane, in August of 1955 led to disastrous flooding in the State of Connecticut. Hurricane Connie dropped four to six inches of rain on Connecticut between August 11th and 12th. One week later Hurricane Dianne dropped an additional twenty inches of rain on the state. With the Seth Thomas Clock Company infrastructure located on both banks of the Naugatuck River in Connecticut, the factory and business offices were devastated by the storms and the severe flooding.  Most business records were destroyed, and the factory was forced to reduce, and eventually stop, production. From that time on Seth Thomas imported its clock movements from Germany, ending its standing as a manufacturer of American Clocks.
