Rolex began producing the reference 6240 in 1965, making it the first model the brand produced with a black acrylic bezel and screw-down chronograph pushers. These pushers and screw-down winding crown were an improvement over the water-resistance of previous references. At the time, the model was not received as well as anticipated, and production of the reference ceased after only four years, in 1969. It is estimated that in that time, less than 2000 examples were produced, all in stainless steel.
The 6240 is also notable for being the first Rolex Daytona model to have the “Oyster” designation on the dial – Rolex was able to add this designation to the dial because of the new and improved water resistance. Early examples of this model did not feature this text, only “Cosmograph Daytona”. The present watch is one of the later examples produced, and is in mint condition. At the time of release, many complained about the large chronograph pushers – while today this reference is sought after for that reason. The combination of screw-down pushers, black bezel and dial with contrasting silvered subsidiary dials make the reference 6240 the perfect combination of dress and sport. The rarity of the present watch is further enhanced by the Sigmas located on either side of the “T Swiss T” designation – indicating that the indices on the present watch are white gold, as opposed to the standard stainless steel. An opportunity not to be missed, the present example will be appreciated for years to come by discerning collectors.
