Rolex GMT Master

Built for people who are never in just one time zone, the GMT-Master started life in the 1950s as a tool for Pan Am pilots crossing the Atlantic. The trick is simple and genuinely useful: an extra arrow-tipped hand and a 24-hour bezel that together let you read a second time zone at a glance, so you always know what time it is back home. The two-tone bezels are where the fun lives, and where the nicknames come from, the red-and-blue "Pepsi," the blue-and-black "Batman," the brown-and-black "Root Beer." You'll find it in steel, two-tone, and gold. It's the traveler's Rolex, and one of the most recognizable watches on the planet.
