How do you identify a Seth Thomas clock?

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 you tell the date on a Seth Thomas clock?

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.
