The present watch is a very rare example of a reference 6240 that is very collectable, and in lovely original condition. With a 1.4 million serial number, it was released in the early batch of watches introduced for this reference and, as such, features a very rare dial.
Known as the Jumbo Daytona, Rolex experimented with different dial configurations before becoming satisfied with the reference 6263 and 6265. While earlier Daytona models featured a small Daytona script below "Rolex Cosmograph", Rolex also introduced a different dial configuration displaying a slightly larger "Daytona" font. It was only much later that Rolex printed the "Daytona" designation above the subsidiary register positioned at 6 o'clock. In addition to the outstanding condition of this example, the subsidiary registers have begun the ageing process and are turning brown, contrasting against the bold white graphics.
