The new Rolex Oyster Perpetual Air-King ref. 116900 was without a doubt, one of the most surprising releases by the 'Green Giant' during Baselworld 2016 earlier this year. Along with the new Daytona with Cerachrom bezel ref. 116500LN we featured here, the new Rolex Air-King ref. 116900 was the other watch at the Rolex booth that took most of the attention from journalists, retailers and collectors.
