Hamilton has an aviation heritage dating back to 1919. A major highlight of the era was the selection of Hamilton as timekeeper for the United Air Lines inauguration of the first coast-to-coast service – a 15-hour, 20-minute trip between New York and San Francisco.

Hamilton has an aviation heritage dating back to 1919. That was the year in which a Hamilton aeronautical watch accompanied the very first American airmail postal service between Washington and New York. This in-flight activity continued to strengthen and grow and by the 1930s Hamilton was the official watch of the commercial airlines, TWA, Eastern, United and Northwest. A major highlight of the era was the selection of Hamilton as timekeeper for the United Air Lines inauguration of the first coast-to-coast service – a 15-hour, 20-minute trip between New York and San Francisco. Today the Hamilton range includes various aviation-inspired watches. The brand is also timekeeper to a variety of international aviation events and has Nicolas Ivanoff, the leading French aerobatic pilot as its ambassador.
Make crucial flight calculations via the slide-rule bezel. Hamilton extends its range of pilot watches with models that make conversions and calculations easy.
The watch’s distinguishing feature is a bi-directional rotating bezel, whose logarithmic gradations interact with the fixed scale around the dial, creating a ‘slide rule’ enabling mathematical calculations while in flight. This can be applied to critical factors like airspeed, distance, fuel consumption, rate of climb or descent and flight time – in fact, it follows the same principles as the E6B “Whiz Wheel”, a paper flight computer that’s still used widely in pilot training today.
The slide-rule bezel is also handy for carrying out various unit conversions: kilometers/nautical miles, pounds/kilograms, feet/meters for instance, or currency conversions for those flying internationally.
