Seth Thomas Regulator No. 7 long version. An antique wall clock. 220021

This 1-weight wall timepiece is a very difficult model to find. It was originally offered in two case sizes, a short and a long version. The movement varied depending on which version you purchased. The cases were constructed in either walnut, cherry or oak. This model was cataloged in 1896.

This example is constructed in walnut and is considered the long version. It measures approximately 48 inches in length and is approximately 3 inches longer than the shorter version. It is my experience that the long version is more difficult to find and has exhibits proportions that the shorter examples. The finish appears to be original and is in excellent condition. The case is decorated with numerous carvings that are worked into the form. The upper door access the dial. This is a zinc dial that measures 12 inches in diameter. This is the original zinc pan. It has been professionally repainted in the early 1970’s by the Dial House in Georgia. This dial features a large Roman style hour numerals positioned inside a closed minute track. A subsidiary seconds registrar and the Maker's trademark are positioned in their traditional locations. The 72 beat movement is brass and of good quality. The plates are in the shape of a trapezoid and are polished. Four posts with blued screws secure the frames. Cut steel pinions support the brass gearing. The escapement is a "Graham Deadbeat." It is weight powered and is designed to run eight-days on a full wind. The movement features "Maintaining Power so that it keeps time as you wind it." The pendulum is constructed with a wooden rod and a zinc bob which is covered in brass. The brass bob and weight are treated with a nickle finish. The bob is decorated with the traditional Seth Thomas pattern. Note this clock retains its swing indicator which is mounted to the backboard of the case.

This clock measures approximately 48 inches long. It is 18.25 inches wide and 7.75 inches deep. It was made circa 1896.

For reference, see Tran Ly’s book titled Seth Thomas Clocks and Movements, page 285. This clock measures approximately 48 inches long.


About Seth Thomas of Plymouth and later Thomaston, Connecticut.

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, though 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 changed over to brass from wooden movements. He made the clock that is used in Fireman’s Hall. He died in 1859, whereupon 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.
