ウォルサム
The earliest incarnation of the Waltham Watch Company was founded on this site in 1854, and demonstrated the complete creation of a watch under a single roof. The company went through a number of management and ownership changes, and was known as the American Waltham Watch Company when the first buildings of this facility were constructed beginning in 1879, when some of the first buildings were demolished. They were lauded at the time as model facilities, dedicated to the safety and hygiene of the workers, and included amenities such as daycare facilities that were unusual for the time. Major modifications to the plant ended in 1913, and the plant was shutdown about 1962, after a series of financial difficulties and ownership changes.
