Guide to the Jon and Jennifer Hanson Watch and Clock Collection

Scope and Contents

The initial collection consists of approximately 760 photographs and negatives created by the Hamilton Watch Company and documenting its employees, equipment, materials, and factory in Lancaster, Pennsylvania. Many photographs depict the company's research and development efforts. There are also images of the Hamilton Watch Company's work in fuse assembly for bombs during WWII. The photographs are mainly organized by factory department or location. A number of these photographs were created by the advertising department and include identification numbers, location of the image, name of the photographer, and the identification of people in the photograph, as well as release forms for those pictured. If not located with the photographs, these items, as well as additional information, can be found in the corresponding folders. Negatives in poor condition were scanned. There are also five glass plate negatives.

Following addenda consist primarily of advertising material related to material catalogs and newspaper and magazine articles published by watch companies in the 19th and 20th centuries. Included in the addenda are photographs, correspondence, articles, and other material documenting the interior operations, products, and horological research relating to the Hamilton Watch Company, Bowman Technical School, Keystone Watch Case Company, Elgin National Watch Company, United States Watch Company, Waltham Watch Company, and other prominent watch manufacturers primarily in the 20th century.

Biographical / Historical

Hamilton Watch Company, established in Lancaster, Pennsylvania, in 1892, was known for its manufacture of high quality wrist and pocket watches. Broadway Limited, its first series of pocket watches, was nicknamed "the watch of railroad accuracy," and Hamilton soon became associated with the railroad industry. The company also supplied wristwatches to the United States Armed Forces in the 1910s. Hamilton continued its association with the military during World War II when it stopped production of watches for consumers in order to provide the armed forces with one million timepieces. The company was responsible for the Ventura, the world's first electric (battery-powered) watch, and in 1970, the world's first digital watch.

In 1969, Hamilton closed its factory in Lancaster, Pennsylvania, signaling the end of its American manufacturing operations. All production moved to the facilities of the Buren Watch Company in Switzerland, a company that Hamilton had acquired three years before. The Hamilton brand is currently owned by the Swatch Group and carries two product lines, American Classic and Khaki.
