Seth Thomas Records

Seth Thomas Company Tower Clock Records, Thomaston, Connecticut.


These volumes record the tower clocks produced and sold by the Seth Thomas Tower Clock Company from the years 1873 to 1941. This project has been generously funded by several NAWCC Members and Chapters.

The documents are very large files; therefore, please be aware that they will take time to load depending on your internet connection. Due to copyright restrictions, users are requested not to print or copy images except for their own personal use. These records are also available for viewing at the NAWCC Library and Research Center. Adobe Reader 7.0 is required to view these files.


Seth Thomas Tower Clock Installations

Thanks to a recent donation we now have a list of the Seth Thomas Tower Clock installations, both domestic and foreign. The list is organized first by state and then by country and shows dates, places, and a short description of the movement for (as far as we can tell) all of the Seth Thomas Tower Clocks. We also have a list of places where the Seth Thomas movement was replaced by an International Time Recording Master Clock between 1924 and 1927. The list was initially sent to the head of General Time after they acquired Seth Thomas and we are very excited to be able to make it available. Due to the size of the document it has been split into two parts.
