Rolex GMT-Master II

In 1954, Rolex created the GMT-Master for Pan Am pilots so they could track two time zones at once. The GMT-Master II can now display three and boasts a sapphire crystal, a ceramic bezel, and a movement immune to the effects of magnetism and shock. It remains the quintessential traveler's watch, whether you're in the cockpit or in coach. [$10,400; rolex.com]
