The National Watch and Clock Museum (USA) (NWCM), located in Columbia, Pennsylvania, 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.
Like its subsidiary institution, the NAWCC Library & Research Center, the National Watch and Clock Museum is operated by the National Association of Watch and Clock Collectors (NAWCC), a non-profit organization with about 21,000 members and an educational mission. The National Watch and Clock Museum was founded in 1977 by the NAWCC and over time has put together a major collection of horological artifacts, mainly clocks and watches, but also related tools, machinery and ephemera, and has become an important institution in its field.
Most of the greatest and most important clocks and watches ever made have been preserved and exhibited — for decades if not centuries — as decorative art in such major museums around the world as the British Museum in London or the Metropolitan Museum in New York, or form a small department in the globally important museums of technology and science such as the Smithsonian Institution, the Musée des Arts et Métiers or the Deutsches Museum. There are only few museums like NWCM, dedicated principally to the history of timekeeping, and the majority of them - located in former centers of horological production - have primarily a local or regional focus. Since the former "Time Museum" in Rockford, IL closed in the 1990s, the NWCM is often described as the broadest specialist horology museum in the country. (The only comparable museum in the United States is the American Clock & Watch Museum in Bristol, Conn., but that one is more focused on American-made timekeepers).
The museum, located on the fringe of the Pennsylvania Dutch tourist area, serves both a general public (including youth), as well as a specialised audience of horological aficionados (including NAWCC members), which appreciate its study collection and some of the more specialized temporary exhibits.(Wikipedia)
