The Rolex Air-King pays tribute to the pioneers of flight and the role of the Oyster in the epic history of aviation. With its 40mm 904L steel case, solid link Oyster bracelet with Oysterclasp and distinctive black dial, the new Air-King is as functional as it is timeless. Updated for the modern wearer while retaining the aesthetics of the 1950s model, the new Oyster Perpetual Air-King continues the aeronautical heritage of the original Rolex Oyster.
