Seth Thomas Antique Clock Repair

Seth Thomas Clock Company was one of the most prolific and long lived clock companies. The quality of their products was always maintained at an above average level. Seth Thomas must have sold many clocks in the Lafayette, Indiana area, for out of all the antique clocks we repair, about 40% are made by Seth Thomas.

Many American clock factories in the 19th century suffered factory fires but Seth Thomas was fortunate in this respect. Through conservative growth and taking advantage of the new ideas of others, Seth Thomas was able to enjoy financial stability, whereas many other companies faced financial difficulties.

The most popular Seth Thomas mantel clock movement is the No. 89. This movement was used in mantel and shelf clocks and from about 1900 to 1940. Before that, a movement with the escapement at the back was used in Seth Thomas mantel clocks. Both of these movements can be overhauled for $300 - $400. The No. 89 movement is one of the best mantel clock movements ever designed. It uses thin mainsprings (about .017") to prevent excessive wear, and makes efficient use of power by having a semi-deadbeat escapement.
