✦ Overview

This striking octagonal Seth Thomas wall clock exemplifies classic American clockmaking, featuring a richly aged hardwood case, elegant Roman-numeral dial, and a warm three-rod bim-bam strike that sounds the hour with clarity and restraint.

To eliminate the maintenance concerns typically associated with century-old movements, the original mechanism has been professionally replaced with a brand-new German mechanical movement, making this clock as dependable as it is beautiful.

An ideal choice for collectors, designers, or anyone seeking an authentic antique wall clock that is ready to hang, reliable, and worry-free.
