Hamilton

Hamilton Watch Company was founded in Lancaster, Pennsylvania in 1892. The company became known for precision railroad watches. Hamilton launched the world's first electric timepiece in 1957 and the first LED digital watch in 1970. Its watches synchronized railroads, furnished the wrists of soldiers and aviators, and have appeared in over 500 Hollywood films. Hamilton acquired Swiss manufacturer Buren in 1966 and closed its Lancaster factory in 1969, moving all production to Switzerland. The company was sold to SSIH in 1974, which later merged with ASUAG to form what became the Swatch Group. Today Hamilton operates from Biel/Bienne, Switzerland.
