The Rolex Air-King reference 14000 is understated with a modest 34mm Oyster case, stainless steel, and a flat-link Oyster bracelet. But don't let the subtle style of this luxury watch fool you, it comes from pretty impressive beginnings. Rolex developed the Air-King during the height of World War II. Its design was inspired by a preference among the British Royal Air Force for Rolex Oyster Perpetuals. The result was the sleek and sophisticated Air-King that is powered by a perpetual movement and waterproof up to 330 feet. Impressive enough for formal affairs yet also suitable for everyday wear, the Rolex 14000 is bound to become your new go-to piece.
