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. It bears the name Air-King in the same lettering that was designed specially for the model in the 1950s.
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.
The Oyster bracelet
The Oyster bracelet is a perfect alchemy of form and function, aesthetics and technology, designed to be both robust and comfortable. It is equipped with an Oysterlock folding clasp, which prevents accidental opening and the Easylink comfort extension link, also exclusive to Rolex. This ingenious system allows the wearer to increase the bracelet length by approximately 5 mm, providing additional comfort in any circumstance.
All Rolex watches are assembled by hand with the utmost care to ensure exceptional quality. Such high standards naturally restrict Rolex production capacity and, at times, the demand for Rolex watches outpaces this capacity.
Therefore, the availability of certain models may be limited. New Rolex watches are exclusively sold by Official Rolex Retailers, who receive regular deliveries and independently manage the allocation and sales of watches to customers.
Siam Swiss is proud to be part of the worldwide network of Official Rolex Retailers and can provide information on the availability of Rolex watches.
The Oyster Perpetual Air-King pays tribute to the pioneers of flight and the Rolex Oyster’s role in the epic story of aviation. With its 40 mm case in Oystersteel and distinctive black dial combining large 3, 6 and 9 hour numerals with a prominent minutes scale for optimal navigational time readings, the Air-King perpetuates the aeronautical heritage of the original Rolex Oyster.
