Lancaster Watch Company
Also known as: HMW Industries
Why it's listed
Built between 1874 and 1963 in Lancaster, Pennsylvania, this complex of more than two dozen red brick buildings occupies a single city block bounded by Columbia, West End, Race and Wheatland Avenues. Four stories high with clock towers topped by mansard roofs, its main wings give the plan an E shape. The company began as the Adams and Perry Watch Company in 1874, and by 1877 had produced the first American watch movements with a double escapement. Incorporated as the Hamilton Watch Company in 1892, it became a leading American timekeeper maker, supplying accurate watches to railroad personnel and producing marine chronometers in both world wars. In January 1957 it introduced what the nomination describes as the world's first electric wrist watch. The buildings combine Second Empire, mill and warehouse, Art Deco and International Style features into a unified group, with red brick, regular bays and corbelled cornices tying the later additions to the original 1874 section.
Significance in brief: The nomination argues the complex is significant for its role in American watchmaking and industrial history, including the first large-scale production of several horological inventions and wartime marine chronometers. It also treats the buildings as notable industrial architecture that combines several styles into a unified whole.

What listing means for this property
For an income-producing building, listing (individually or as a contributing building in a district) is the gateway to the 20% federal rehabilitation tax credit on qualified rehabilitation costs, often stackable with state credits. Work claiming the credit must follow the Secretary of the Interior's Standards and be approved in advance.
Listing does not restrict a private owner acting without federal money or permits; where federal funding or licensing is involved, Section 106 review applies.
