A watch rich in history, the Rolex Air-King first got its name when Rolex founder Hans Hans Wilsdorf, chose to honor the RAF pilots of the Battle of Britain with a series of aviation themed watches. The “Air” series included the Air-Lion, Air-Giant, Air-Tiger, and of course the Air-King. Today, only the Air-King remains. The new Air-King also epitomizes Rolex’s privileged ties with the world of aviation during its golden age in the 1930s. Today’s new Air-King pays tribute to the pioneers of flight and the Oyster’s role in the epic story of aviation.The Air-King’s Oyster case, guaranteed waterproof to a depth of 100 metres (330 feet), is a paragon of robustness. Its characteristically shaped middle case is crafted from a solid block of particularly corrosion-resistant 904L steel. The Air-King is equipped with calibre 3131, a self-winding mechanical movement entirely developed and manufactured by Rolex. Its architecture, manufacturing quality and innovative features make it singularly precise and reliable. The Air-King is fitted on a solid-link Oyster bracelet in 904L steel with a folding Oysterclasp. This bracelet features the ingenious Rolex-patented Easylink rapid extension system that allows the wearer to easily increase the bracelet length by approximately 5 mm, for additional comfort in any circumstance. Truly a watch fit for a king, the Rolex Air-King is the superior timepiece you need to wear on your wrist today.
