Seth Thomas Clock Co. “Drop Octagon”, ca 1921.
This is an 8 day time and calendar movement but there are no calendar wheels on the movement. Collectors tell me you can get the calendar parts from Timesavers or other parts houses. The painted metal dial is original, and has slight wear and grime. This is a mahogany case that is 23″ high, complete and original. The hands, small glass, and brass pendulum are all correct. The large glass is not original. The 8 day movement is signed, running, and still has the Geneva stops. Inside is a complete paper label. Ly-Seth Thomas No. 246.
