The Hamilton Khaki Aviation Pilot Day Date gained significant cultural status after its prominent feature on the wrist of the character "Cooper" in the 2014 film Interstellar. Its design, however, is drawn directly from the brand's heritage as an official supplier to commercial airlines in the 1930s. The dial architecture strictly follows a "Type B" flieger layout, prioritizing the outer minute track for navigational legibility, balanced by the arched day complication at 12 o'clock. This reference is powered by the Calibre H-40, a technically modified ETA base movement, which is regulated to a lower frequency to achieve an extended 80-hour power reserve.
Established in Lancaster, Pennsylvania, in 1892, Hamilton's pocket watches are an essential instrument of American industrial expansion. Its initial reputation as "The Watch of Railroad Accuracy" was earned by producing pocket watches of such reliability that they became critical tools for synchronizing the nation's railways. Their legacy was further solidified during World War II, when Hamilton ceased all civilian production to supply over one million timepieces to the U.S. military, creating the utilitarian design template for its iconic Khaki Field collection. In the post-war era, Hamilton introduced one of the world's first battery-powered electric watch in 1957—housed in the landmark, asymmetric Ventura—and later debuting the Pulsar, the first-ever digital electronic watch. This history of American innovation is now paired with Swiss manufacturing as part of the Swatch Group.
