As a direct descendant of the original released in 1945, this Air-King bears the hallmarks befitting a classic timepiece. The original design was intended for pilots, both commercial and military. The look was simple and legible, while maintaining the robust demeanor and quality expected from Rolex. This version dates to 2007. This is important because it has the traditional case size of 34mm and a clean 3 6 9 silver dial. The addition of solid end pieces and a machined clasp are subtle improvements that are discreetly tucked away out of sight. This classic charmer comes with the original, clean Rolex guarantee card..
