American Clock & Watch Museum

The American Clock & Watch Museum (ACWM), located in Bristol, Connecticut, is one of a very few museums in the United States dedicated solely to horology, which is the history, science and art of timekeeping and timekeepers. Located in the heart of the historic center of American clockmaking, ACWM is the world's preeminent horological museum in the area of American clocks, primarily industrial-made clocks of the 19th and early 20th century.

The museum is located in a complex including the historic Miles Lewis residence, the partially relocated historic 1728 Barnes homestead, and a modern extension wing in the town of Bristol, Connecticut, the hometown of the former Ingraham and Sessions clock companies. Bristol is located north of Interstate Highway 84, about 30 minutes west of Hartford CT or two hours from New York City.

The ACWM is an independent educational institution, operating under Section 501c3 of the Internal Revenue Code, and besides a small professional staff relies on volunteers for much of its manpower and support. Originally known as The Bristol Clock Museum, the institution was started in 1952 and acquired its site the next year.
