OUR BEST ENGINEERING FOR STYLISH PILOTS
MAKE CRUCIAL FLIGHT CALCULATIONS VIA THE SLIDE-RULE BEZEL
Hamilton extends its range of pilot watches with models that make conversions and calculations easy.
As any professional pilot will attest, there is nothing quite like the freedom of flight – bursting through clouds at 10,000 feet, the cockpit flooding with light as you arc upwards into the clear blue sky. But that freedom is based on technical calculations that a true aviator must be able to make with or without the aid of cockpit instruments.
At Hamilton, we’ve provided the flying community with the precision timepieces they need for over a century, from the first U.S. Airmail service in 1918 to today’s daredevil air racers. With the Khaki Aviation Converter, we’re enabling crucial flying calculations to be performed on the wrist of modern aviators.
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.
Already a powerful tool, the 42mm automatic version of the Khaki Aviation Converter steps up the game with a balance spring made of NivachronTM alloy, an exclusive new material with superior resistance to magnetic fields. In the cockpit, having a watch unaffected by magnetic forces is critical, and by adding this superior balance spring alloy, we ensure precision in any environment. Military pilots’ watches were the first to include anti-magnetic technology that countered the fields generated by radar instruments.
A sleek black dial houses the H-10 automatic movement with 80 hours of power reserve, and is available on a brown and black leather strap or a stainless steel bracelet.
If you’re looking to add even more function to your Khaki Aviation Converter, choose our 44mm GMT designed with a blue dial and available with brown leather strap or bracelet. Powered by our H-14 movement, it includes 80 hours of power reserve, perfect for the globetrotting adventurer.
The Khaki Aviation Converter Automatic Chronograph rounds out the collection with its H-21-Si movement. Using a high-tech silicon balance spring, it negates the powerful magnetic forces found around airplane cockpits and flight decks.
The Khaki Aviation Converter is a combination of Swiss engineering and high demanding aviation equipment.
