Seth Thomas Clock Company

The Seth Thomas factory made countless clock movements during and prior to the second world war. The high quality standard made the company a great success. After the war they stopped making any movements and used alternate makers for there Seth Thomas clocks. So the clocks were Seth Thomas but the clock movements were made in Germany instead. The German movements used by Seth Thomas were made by Hermle clock company or Kieninger. Seth Thomas only married them to these units to the clock cases and sold them under there company name.

A long History

The Seth Thomas had a long history of clock making. The name ended up being exchanged from one company to the next through the years, and is now extinct.

End of Seth Thomas

As you can see, the Seth Thomas Clock Company had a long run and a wild ride. The company name may now be found on silly things like lighters and some quartz clock dials. What we offer and sell is the German ST units made in Germany. These are the units General Time and Tally Industries sold under the Seth Thomas name they owned, and put Hermle clock movements in the clock cases. These German units are high quality and last 25-30 without much complaint.
