Antique Seth Thomas World 15 day Clock
Jul 2021 – #99 Antique American Clocks Seth Thomas “World”, ca. 1910. ST made these clocks with 15-day and 30-day time-only movements; I think this is a 15-day model but cannot be sure without running it for the duration. The 32-inch case is veneered in oak with a medium stain and a clean but old finish. The dial glass is old but possibly a replacement; the lower glass is likely original with gilt trim. The dial is beginning to flake and is faded and lightly soiled. The hands are correct. The double-spring movement is signed (behind the crosspiece) and is running with the correct pendulum bob and stick. There is a white label on the backwall just below the dial, and a brass beat scale at the bottom. A date stamp of 1907 on the back but it looks suspicious. These clocks ain’t as popular as they used to be, when everyone had to have one. Several recent sales at $225.
