The main block occupies one city block bounded by Columbia Avenue, West End Avenue, Race Avenue and Wheatland Avenue, and was developed from 1874 to 1963.","why_significant":"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.","narrative":"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.","period_of_significance":"1874-1963","architect_builder":"Many; see Appendix II for the Builder/Architect entries; the 1874 building was designed by C.
