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.
