This 40mm Air-King has a really cool 3, 6, 9 dial interspersed with 5 minute increments, giving the appearance of a racing speedometer. Another nice little touch, if you look closely, is that the three larger numbers are applied whilst the rest are printed giving a really nice depth to the black dial. In a 40mm Oystersteel case and powered by the Chronometer certified automatic 3131 movement, it comes presented with its original Rolex box, instruction booklet, swing tags and the all important Rolex warranty card.
