In 2016 Rolex introduced the Oyster Perpetual Air-King, a watch that perpetuates the aeronautical heritage of the original Rolex Oyster. The new Air-King, with a 40 mm case in Oystersteel, features a distinctive black dial with a combination of large 3, 6 and 9 numerals marking the hours and a prominent minute scale for navigational time readings. The dial bears the name Air-King in the same lettering that was designed specially for the model in the 1950s.
