Seth Thomas Regulator No. 18 wall regulator in light oak. 221097

This is the Grand-daddy of the school clock form. A form which all American clock collectors recognize. This large oak cased wall clock measures approximately 54 inches long, 20.25 inches wide and 5.5 inches deep. Big regulators like this one are visually pleasing. The gentle motion of the seconds beating pendulum is a sight to see.

This is an oak cased example. The oak wood is a light color. It is bright and clean. The bezel is in excellent condition. It is fitted with glass and the glass is held in place with a brass trim ring. Tis protects the dial. The painted dial measures 14 inches in diameter and is painted on a zinc pan. This is in excellent original condition which is remarkable for a Seth Thomas clock. The dial is formatted with a time track that displays the hours with Roman numeral style figures, a closed minute ring with triangular shaped five minute markers, a subsidiary seconds dial is located above the center arbor, the Maker’s name is printed in block lettering and is displayed just above the six o’clock hour and the statement, “MANUFACTURED IN THE UNITED STATES OF AMERICA” is located at the bottom of the dial below the time ring. The movement is brass and is very good quality. The movement is weight powered and is designed to run eight-days on a full wind. It incorporates both a Graham deadbeat escapement and maintaining power. This movement is secured to the case by an iron bracket that is screwed to the backboard. The pendulum also hangs from this bracket. The pendulum is constructed with a shaped wooden rod (painted black) and a large brass covered bob. The weight is also covered in a brass sleeve matching the finish found on the bob. An engraved brass swing indicator is mounted behind the bob onto the backboard. In the bottom of the case, you will find the manufacture’s label.

This clock was made circa 1905.


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.
