Hamilton designed the Khaki Aviation X-Wind GMT Chrono Quartz H77932160 to take on turbulent skies, and the green dial gives this version a bold, military-inspired character. Large Super-LumiNova numerals and cockpit-instrument style hands sit on top, with high contrast that makes every function easy to read.

Few watches pack in this much capability. There’s a GMT hand for tracking a second time zone, a chronograph for timing, a date, and the X-Wind’s signature crosswind calculator, an aviation tool Hamilton developed to help pilots work out the effect of wind on a flight path. The Swiss quartz caliber G10.962 runs it all with grab-and-go accuracy, so there’s no winding or setting after a few days off the wrist.

The 46mm stainless steel case measures 13.75mm thick and is fitted with a screw-down crown for 100 meters of water resistance. On its matching stainless steel bracelet with folding clasp, it’s a rugged, all-metal travel watch that looks equally good on the flight deck or in the departure lounge.
