Rolex Air-KingThe RAF pilots were honoured for their duty in 1945, when Rolex founder Hans Wilsdorf named a series of Oyster watches after them. The Air-Lion, Air-Giant and Air-Tiger might not sound familiar as they were discontinued shortly after production. However there is one model still being produced, even after 70 years: the Air-King. Over the years Rolex kept refining the Air-King and they continued to issue new reference numbers. All the different reference numbers have somethings in common. They are all simple designs, executed in steel, and with a no-nonsense reliable movement. Although it has always been among the least costly models from Rolex, it is loved by many watch enthusiasts.
