The American Waltham Watch Company Historic District encompasses the former factory of the Waltham Watch Company, the leading American watch manufacturer of the 19th century and the city's largest employer. Located on Crescent Street and the banks of the Charles River, the surviving elements of its manufacturing facility date from the 1870s to the 1910s, and include particularly fine industrial Romanesque architecture. The buildings have been converted to a variety of commercial, industrial and residential uses since they ceased being used for watchmaking in the 1950s. The complex was listed on the National Register of Historic Places in 1989.
