During the 1930s Rolex’s Oyster was preferred by trailblazers in aviation including the record-breaking Charles Douglas Barnard and the pioneering Owen Cathcart-Jones and Ken Waller. The brand built on the iconic watch’s legacy with quality and precision in mind. The new Oyster Perpetual Air-King’s case is made from corrosion-resistant c904L stainless steel and is water resistant to 100 meters. Powered by Rolex’s self-winding mechanical Calibre 3131 with 48 hours of power reserve, the Air-King’s performance is only matched by its sleek design—the dial, black with a satin finish, features bold numerals in 18-karat white gold.
