220094 Seth Thomas GALLERY 24-INCH. The Big One. William Ashall’s clock. A Watchmaker & Jeweler circa 1865 in Toronto, Canada.

This large example is a difficult model to find in excellent condition. This model is cataloged as the “GALLERY 24-INCH.” It was made by the Seth Thomas Clock Company and offered in their catalogs as early as 1884.

This is an excellent example. The case is constructed in oak and has recently had its finish wonderfully enhanced. The golden oak color is a pleasing color. The back of the case measures 32 inches in diameter. The front of this case is actually a door. This door or wooden bezel is fitted with glass and protects the dial. The dial is painted on zinc and measures 24 inches in diameter. This dial is original to this clock and is in very good overall condition. It has been maintained. There are a small number of areas where the white background color has been restored. The hours are displayed in large Arabic-style numerals. These are presented in a tumbled or upright formatting around a closed minute ring. Diamond-shaped markers are positioned at the five-minute positions. Both hands are steel and nicely formed. The minute hand is counterbalanced. The movement is a double spring time only design. It is designed to run for thirty days on a full wind. The movement is brass and features a Graham deadbeat escapement and is secured to an iron bracket, which is mounted to the back of the case. The pendulum hangs behind the movement and the dial. Its access is somewhat limited. As a result, a pendulum starter or kicker is accessed through the dial just above the company’s name. Insert your winding key in this hole and turn it clockwise to start the pendulum in motion. Below the large Arabic hour numeral XII is the speed manual adjustment. Insert your key here, and one can slow or speed up the clock depending on the direction you turn the key. This clock was made circa 1910.

This clock was originally owned by William Ashall, a watchmaker and jeweler located at No. 147 Yonge Street in Toronto, Canada. His business was listed as early as 1865. It was also listed in the Jeweler’s Circular and Horological Review in 1891 when he announced that he had given up his Jewelry business and was now the caretaker of the civic clock for the city of Toronto.


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.
