Book 6 Seth Thomas covers the most popular movements produced by this well-known American clockmaking dynasty. Seth Thomas clocks rank high among repairers for quality and durability. Collectors are often attracted to Seth Thomas clocks for the same reasons, and this manufacturer’s name is more recognizable to the general public than any other. Seth Thomas (1785-1859) started work in the clock manufacturing business in the early 1800’s. The company is best known for the clocks made during the American mass production era, extending from the late 1800’s until the early 1950’s. Chapter 1 is devoted to the No. 89 strike movement, which is one of Seth Thomas’ most plentiful movements. Chapter 2 covers the main chime movements made by the company. These are the No. 113, the No. 124, and the Sonora Chime. Chapter 3 contains material on the early, difficult-to-repair ship’s bell movement. Chapter 4 features a variety of movements which strike the hours only, or the hours and half hours. These made up the largest share of Seth Thomas production. Chapter 5 includes material on simple, early alarms attached to movements. There are also articles on the Long Alarm and the Automatic Eight-Day Alarm. Chapter 6 covers several timepieces, that is, mechanisms which do not strike or chime. The material in the book is based on features from the editor’s Clockmakers Newsletter, the monthly clock repair publication produced from 1987-2008.
