About the Seth Thomas “Office No. 6” Clock
The Seth Thomas “Office No. 6” clock, produced around 1909-1913, is an antique American timepiece that showcases the craftsmanship of the renowned Seth Thomas Clock Company. This 36-inch mahogany or oak case clock boasts a potentially original dark finish and features an old dial with painted numbers, both glasses, and a time-and-strike movement that runs smoothly for eight days, striking on a wire gong.
The clock’s design includes an etched top and base, which adds a touch of elegance to its otherwise plain appearance. The original red mahogany finish on the case has never been cleaned or refinished, maintaining its aged character with visible crazing on the wood. Some listings suggest that the glasses may not be original, while others indicate that the dial was repainted to resemble an original design found in books.
The Seth Thomas “Office No. 6” clock was marketed as a competitive alternative to store regulators and shop clocks produced by other manufacturers. The company offered the option of removing the etched top if a plainer case was preferred, making it versatile for various settings. Despite its age, this antique timepiece remains in good condition, with some minor wear and tear that adds to its unique charm.

Antique Seth Thomas Office No. 6 Clock
Jul 2021 – #63 Antique American Clocks Seth Thomas “Office No. 6”, ca. 1913. A 36-inch mahogany case with a dark and possibly original finish. Both glasses are old, as is the painted dial and dial board. The Seth Thomas time-and-strike movement is dirty but runs without problem, 8 days, striking on a wire gong. A dark label inside on the bottom. This model came as time-only, time-and-strike, and with a calendar. ST advertised that the top could be removed if you wanted a plainer case. Seems pretty plain already to me

C.1910, Seth Thomas “Office No. 6” oak cased store regulator in very good condition, time only.
The only thing that keeps this from being excellent is the fact that someone lightly varnished over the entire case giving it a syruppy look (original finish in intact beneath, and some 4 ought steel wool would take this off with some patient rubbing). As the catalog states, the top may be removed if a “Plain Case is Preferred”. This clock sold for 8 dollars in 1910. Retains original, dial, hands, movement, finish and metal index inside bottom of case. Also with original label inside, that has been varnished over like the rest of the case. Actually looks quite decent as is. Height 36 inches

Seth Thomas “Office No. 6”, ca 1909.
No doubt made by ST to compete with the poplar store regulators and shop clocks made by the other clock makers.They said in their ad, “Top can be taken off if a plainer case is preferred”.The Office No. 6 with the etched top and base was a little fancier than theIngraham or Sessions comparable cases. ST priced their No. 6 to be competitivewith the other companyÕs store regulators. Today the ST No. 6 will sell fortwice as much as the competitions comparable clocks. They also made the sameclock with a simple calendar. This old oak case has the original crusty finish, case is 36″ high. Movement is 8 day time only; 12″ dial has a little flaking.Runs very strong, has a good label inside, original pendulum. Lacking onlythe brass dial ring to complete the clock. Ly-Seth Thomas No. 473.

Seth Thomas “Office No. 6”, ca 1909.
Their entry in the store regulator race. Other companies made zillions of “shop regulators”, “store regulators”, around the turn of the century, and made them plain and simple. Seth made theirs to be a little nicer and not as large. After 100 years the ST will sell for twice as much as the Ingrahams, Gilbert, etc. This original case has a crusty finish, is 36 inches high. Sporting an 8 day movement, time only, running very strong. 12 inch dial with a little flaking, no dial ring, good label inside, and original pendulum. Ly-Seth Thomas #473. Because of the dial ring our estimate is lowered considerable below current prices. $350- $450.

Case is 32.5 inches high, dial is 12 inch. Ly-Seth Thomas #473. I think you will find the new Ly-Seth Thomas coming out later this year will show the value of this clock around 850 dollars. My estimate .
