If you travel often or keep an eye on a second time zone, the Hamilton Khaki Aviation X-Wind GMT Chrono Quartz H77912135 puts everything you need on one oversized, highly legible dial. Hamilton pitches it at pilots and passengers alike, and it needed a 46mm stainless steel case to fit all of its aviation features, so the black dial has real cockpit-instrument presence.

Three functions do the heavy lifting: a GMT hand for a second time zone, a chronograph for timing legs of a journey or a lap at the track, and a date. Hamilton also highlights the X-Wind’s crosswind calculator, a nod to the drift-angle calculations real pilots make when wind pushes an aircraft off course. Driving it all is the quartz G10.962 caliber, so the watch is accurate, grab-and-go and never needs winding.

A steel bracelet with folding clasp completes the tool-watch look and keeps it secure through airport security lines and long-haul flights. At 13.75mm thick it’s substantial, so it suits larger wrists and anyone who wants a watch that’s easy to read in a hurry.
