The Hamilton Khaki Aviation Converter Auto GMT is a prime example of the brand's dedication to pilot's watches. A truly modern entry into the genre, it features two outstanding features for pilots and the jet-set: a conversion bezel and a "true" GMT complication. The bezel is essentially a slide-ruler which can be used to convert and calculate all sorts of data on the fly, including mph to kph or even currency. The "true" GMT, however, is the star of the show. A version of the GMT complication that used to only be available on higher-priced watches, it allows for the hour hand to be jumped back or forth, without effecting the minutes hand, upon entering a new timezone. 

The watch itself then has a commanding presence at 44mm. The case is exceptionally crafted, featuring gently curving contours, elegant brushing, and polished bevels. It's a large watch, but given the amount of information on display, it utilizes the space to convey everything clearly. The metallic blue dial is absolutely gorgeous and features a combination of textures allowing for visual distinction between the lumed hour markers, and the printed 24-hour index. 

Powering the Khaki Aviation Converter Auto GMT is Hamilton’s excellent H-14 Swiss-made automatic movement. With an impressive 80-hour power reserve, it also features a "true" GMT complication, 25-jewels, date, hacking seconds, and a frequency of 21,600bph. The combination of GMT and 80-hr power reserve is exceptional, adding a lot of value to this already superb pilot's watch.
