This model will run for eight days on a full wind. The brass-covered pendulum bob can be viewed through the opening in the painted design on the lower glass in the front of the case.

Seth Thomas was born in Wolcott, Connecticut, in 1785. He was apprenticed as a carpenter and joiner and worked building houses and barns. He started in the clock business in 1807, working for clockmaker Eli Terry. Thomas formed a clock-making partnership in Plymouth, Connecticut, with Eli Terry and Silas Hoadley as Terry, Thomas & Hoadley. In 1810, he bought Terry’s clock business, making tall clocks with wooden movements. He chose to sell his partnership in 1812, moving in 1813 to Plymouth Hollow, Connecticut, where he set up a factory to make metal-movement clocks. In 1817, he added shelf and mantel clocks. By the mid-1840s, He successfully transitioned to brass movements and expanded his operations by building a brass rolling mill and a cotton factory. His clock business expanded until it became one of the “BIG Seven” in Connecticut and competed at every price point, from kitchen clocks to precision regulators. He made the clock that is used in Fireman’s Hall. He died in 1859, at which point the company was taken over by his son, Aaron, who added many styles and improvements after his father’s death. The company went out of business in the 1980s.
