The Air-King dial 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. Rolex uses Oystersteel for its steel watch cases. Specially developed by the brand, alloys most commonly used in high-technology and in the aerospace and chemical industries, where maximum resistance to corrosion is essential.
