Re: Post your Seth Thomas clocks here. Hi, I'm new here, and would like more info about my clock if anyone can help. Dial is wood, hand painted, and says S. Thomas Plymouth. It's a tall case clock, 30 hour wood movement, brass bell, with calendar and second hand. Pendulum is iron, weights are lead filled brass cans. The case is quite simple, spare of ornamentation, but it looks right at home in my old house.
