The Classic vintage Rolex Air-King-Date, circa 1969 ref. 5700. Originally developed and introduced in 1958 the Air King line become the only one that lasted from a slew of other similar Rolex models developed after WWII by Hans Wilsdorf (founder of Rolex) to honor the airmen of the war. The other models were the Air Lion, Air Giant & Air Tiger. Commonly sold only within the Commonwealth countries. The Air King was then developed further to include an automatic self-winding movement and a Date function. This model is automatic and has a beautiful black matt dial. This example includes a beautiful rare tapered and riveted Oyster bracelet with folding clasp. The Air-King-Date was much rarer than the Air-King without date and had an unusual case that is slightly larger at 35mm than the 34mm Air King (non-date version), making it very desirable and a favorite among collectors !
