Seth Thomas Clock Company Clocks

American

Seth Thomas was an industrious clockmaker and pioneer of mass production in the United States. He founded the highly successful Seth Thomas Clock Company, which operated for more than 200 years. Over these two centuries, the company created mantle clocks, wall clocks and table clocks that were known for their masterful craftsmanship and on-trend designs.

Thomas was born in 1785 in Wolcott, Connecticut, to Scottish immigrants. At the time, Connecticut was a growing hub of American clockmaking. Though he left school at an early age, Thomas apprenticed as a carpenter and joiner in Plymouth. In the early 1800s, he made his first clock out of laurel wood from the mountains around his home.

In 1807, Thomas partnered with Eli Terry and Silas Hoadley to form a clock company called Terry, Thomas & Hoadley. Over the next three years, the firm produced around 400 wall clocks. In 1813, Thomas sold his share of the company and moved to Plymouth Hollow, Connecticut, where he established his clock factory. He gained a reputation for producing beautiful grandfather clocks and tower clocks. 

When Thomas died in 1859, his son, Aaron, took over the company. The Seth Thomas Clock Company continued operating successfully for several more decades. In 1913, it produced the four-faced tower clock that still stands in New York City’s Grand Central Terminal. 

In 1875, Plymouth Hollow was incorporated under the name Thomaston in his honor. The company went out of business in 2009.

Questions About Seth Thomas Clock Company Clocks
  • How do you tell the date on a Seth Thomas clock?
    1 Answer
    1stDibs ExpertAugust 20, 2024
    To tell the date on a Seth Thomas clock, look for a code on the bottom or case back. Most pieces will show the year of production first, with the numbers reversed. Then, you'll usually see a letter. These letters correspond to months, with A representing January, B representing February and L corresponding to December. For example, a date code that reads 31F's manufacturing date would be June 1913. If you need help with the dating process, a certified appraiser or knowledgeable antique dealer can assist you. Find a collection of Seth Thomas clocks on 1stDibs.
  • Is the Seth Thomas Clock Company still in business?
    1 Answer
    1stDibs ExpertApril 5, 2022
    No, the Seth Thomas Clock Company is no longer in business.

  • How do you identify a Seth Thomas clock?
    1 Answer
    1stDibs ExpertNovember 26, 2024
    To identify a Seth Thomas clock, check its movement for a maker's mark. You may need to remove the back of the clock to access it. During the 19th and mid-20th centuries, the clockmaker usually used its full name in script or block letters to mark its pieces. Later clocks are more likely to display either an S centered with a diamond or the initials ST positioned in a circle. If you have trouble finding a marking, a certified appraiser or knowledgeable antique dealer can perform the identification process for you. On 1stDibs, shop a collection of Seth Thomas clocks.
  • How do I date a Seth Thomas mantel clock?
    1 Answer
    1stDibs ExpertApril 5, 2022
    To date a Seth Thomas mantel clock, examine the gears inside. If the movement is wood, the production date of the clock is somewhere between 1817 and 1830. Clocks made after 1881 may feature an ink code date stamp on the case back or bottom. A licensed appraiser can provide assistance with determining the exact manufacturing year. Shop a variety of expertly vetted Seth Thomas mantel clocks on 1stDibs.
