A paragon of robustness and reliability, the Air-King’s 40-mm Oyster case is guaranteed waterproof to a depth of 100 metres (330 feet). The middle case is crafted from a solid block of Oystersteel, a particularly corrosion-resistant alloy.
The Air-King is fitted on a three-piece link Oyster bracelet in Oystersteel. This bracelet is equipped with an Oysterlock safety clasp, designed by Rolex and patented, which prevents accidental opening. It is also fitted with the Easylink comfort extension link, which allows the wearer to adjust the bracelet length easily, by approximately 5 mm.
