Legendary model, the reference 16520, was the first chronograph of the Rolex manufacture to be fitted with an automatic movement derived from a Zenith ébauche. Built with a larger case than its predecessors and a sapphire-crystal glass, the timepiece encountered great success and throughout the years has become an icon amongst Rolex collectors.
Of particular interest, the present chronograph features tropical brown subsidiary registers where the original white chapter rings have reacted to sunlight and other environmental factors and have turned into shades of brown. These dials are so-called "tropical" dials and are sought-after by collectors.
