The company was founded in 1892 and in 1900, over 50% of the population had a watch from Hamilton Watch Co in Lancaster, PA. In 1915, Hamilton started the production of the caliber 986. During the art deco period, Hamilton had tremendous success with the “Coronado”, “Spur” and “Piping Rock”. Then came the 982 calibre in the 1930’s and the famous caliber 500. In 1937, the company supplied the US army. In 1966, Hamilton took over Buren watch. In 1969, it stopped to produce mechanical watch in the US. Then came the revolutionary “Pulsar”. Today, the company is own by the Swatch Group.
