History of Hamilton: Hamilton was founded in 1892 in Lancaster, Pennsylvania and by 1912 the first series of pocket watches was being produced aimed at railroad workers to reduce the number of accidents caused by different timekeeping devices of unreliable accuracy. During the Second World War, Hamilton stopped producing watches for the general public and focused on providing the US forces with over one million timepieces.
