Seth Thomas Clocks
The Seth Thomas Clock Company was organized as a joint stock corporation on May 3, 1853 to succeed the earlier clock making operation of the founder. Seth Thomas (1785‑1859) had been manufacturing clocks at the site since 1814.
The Seth Thomas Clock Company was very prosperous into the 20th century and was considered the "Tiffany’s" of Connecticut clock manufacture, even by their competitors. Between 1865 and 1879 they operated a subsidiary firm known as Seth Thomas' Sons & Company that manufactured a higher-grade 15-day mantel clock movement and during that period were major supporters of a New York sales outlet known as the American Clock Company. They also became a major manufacturer of tower and street clocks after 1872 and in between 1915 were manufacturers of jeweled watches.
On January 1, 1931, the firm became a subsidiary of General Time Instruments Corporation and soon passed from family control. The firm's decline was gradual over the next 50 years and culminated in the firm's removal from Connecticut to Norcross, Georgia about 1975. It has been reported in 1988 that the firm is all but dissolved.
