With its 40 mm case in Oystersteel, solid-link Oyster bracelet, and distinctive Black dial, the Air-King perpetuates the aeronautical heritage of the original Rolex Oyster.

Highly resistant to corrosion

Rolex uses Oystersteel for its steel watch cases. Specially developed by the brand, Oystersteel belongs to the 904L steel family, alloys most commonly used in high-technology and in the aerospace and chemical industries, where maximum resistance to corrosion is essential. Oystersteel is extremely resistant, offers an exceptional finish once polished and maintains its beauty even in the harshest environments.
