Reference 6240 can be considered without a doubt one of the most landmark models in the history of Rolex as it canonizes what is now an intrinsic part of the Daytona case architecture - the screw-down pushers - effectively incorporating the "Oyster case" technology into a Rolex chronograph for the first time ever. At the time of its launch in 1965, however, some clients had complains about the screw-down pushers (the most memorable: they would be unpractical with shirt cuffs), thus the model had limited success and production. In fact, pump pushers Daytona cases remained in production for 10 more years (with references 6262 and 6264) before being finally discontinued.

This example of the historical reference is offered in exceptionally original condition. Most notably, the chromed-plated brass pushers would loose their plating - as perfectly exemplified by the present piece - with relative ease and thus would most often be exchanged for service ones. It is more than remarkable to find a specimen still retaining its original pushers. Furthermore, accurate examination of the dial under direct sunlight shows a hint of dark chocolate tropicalization to the right side of the dial. While too subtle to classify the piece as "tropical", the process might go on over time, thus granting the new lucky owner of this timepiece pleasant surprises in the future.
