American Clock & Watch Museum
American factory made clocks in the exhibit at the American Watch and Clock Museum.
American Clock & Watch Museum is one of a few museums in the United States dedicated solely to horology, which is the history, science and art of timekeeping and timekeepers.
The exhibits include clocks (and some watches) from all periods and countries, but the focus of the exhibits is clearly on American clocks.
A substantial part of the exhibit space is devoted to tell the story of Eli Terry and his successors and imitators. Terry pioneered mass manufacturing techniques in the early 19th century by replacing the traditional system of making one clock at a time with handmade parts each adjusted to fit with each other, to using a system of machine-made interchangeable parts, with close enough tolerances that they could be assembled without further adjustment.
Connecticut clockmaking, together with American firearm manufacturing, helped launch the Industrial Revolution.
