Hamilton was founded in 1892 in Lancaster, Pennsylvania, making pocket watches so precise they became known as "The Watch of Railroad Accuracy". During the Second World War it supplied more than a million timepieces to the U.S. Armed Forces, and over a century ago a Hamilton watch flew with the first U.S. Airmail service, the start of its long bond with aviation. Today Hamilton combines Swiss precision with American spirit across its American Classic, Jazzmaster, Ventura, Khaki Field, Khaki Navy and Khaki Aviation collections. Kamal Watch Co. is an authorised retailer of Hamilton watches.
