First launched in 1965, reference 6240 was manufactured exclusively in stainless steel and featured an acrylic bezel that displayed the tachymeter. It was most notably the first “Cosmograph” wristwatch equipped with screw- down chronograph pushers, which provided improved water resistance. Produced for a few years only, reference 6240 eventually evolved to the well-known references 6263 and 6265.<br />Most probably unique and incredibly important, this reference 6240 presents a completely novel and unprecedented way of understanding the “Cosmograph”. To the best of our knowledge, there is no other timepiece that features this dial configuration.<br /><br />This dial also displays a color scheme that we never seen again anywhere in Rolex’s production. Furthermore, its proportions are also quite unique, thanks to its oversized subsidiary dials that nearly touch the outer white seconds track. Any Cosmograph boasting oversized registers is called today a “Big Eye”. This example’s unicorn characteristics are underlined by the fact that the dial omits any Cosmographs and Oyster designation as well as any hint that it belongs to the Daytona family. This layout is truly unlike anything the market has ever seen before.<br /><br />The ancestor of the “Paul Newman”, this timepiece was presumably created before exotic dials were serially produced and during a time when Rolex experimented with various design codes. Thus, “The Neanderthal” provides a rare window into the inner workings of Rolex, enabling collectors to first, imagine what could be, and second, peek into the firm's past to understand the conceptual development and visual history of the Cosmograph Daytona “Paul Newman” design.<br /><br />Other interesting features of note are the correct first series pushers, with the brass peeking through the pushers, having aged with patina over time giving the wristwatch a lot of character. The watch furthermore retains its original twinlock 700 series winding crown, characterized by only the Rolex coronet.
Case/bracelet: The case is in excellent condition with very well defined finishes on the top of the lugs and crisp edges. There are a very few light surface marks on the case, particularly on the top of the lugs. The caseband and case back has surface wear and displays a crisp finish on the edge. The case has seen very very light polishing only. The Mk 1 pushers show a bit of brass and have aged. The Mk 1 bezel is in excellent condition. The bracelet is in excellent condition has light surface wear and measures 200mm. maximum length. Dial: The dial is in very good condition. The three subsidiary registers show signs of aging (greyish clouds), particularly on the outer concentric rings. There is a honey colored spot on the left sub register. The outer ring shows some signs of aging and has some marks in places. There are some light signs of wear to the lower left portion of the black dial. It seems that all the luminous dots have fallen off at some point, and a remnant is still visible at 1, 2, 4, 5, 6 and 7 o'clock. Movement: The movement is in excellent condition and the chronograph is functioning.

6240 "The Neanderthal"
<p>Founded in 1905 England by Hans Wilsdorf and Alfred Davis as Wilsdorf & Davis, it soon became known as the Rolex Watch Company in 1915, moving its headquarters to Geneva in 1919. Like no other company, the success of the wristwatch can be attributed to many of Rolex's innovations that made them one of the most respected and well-known of all luxury brands. These innovations include their famous "Oyster" case — the world's first water resistant and dustproof watch case, invented in 1926 — and their "Perpetual" — the first reliable self-winding movement for wristwatches launched in 1933. They would form the foundation for Rolex's Datejust and Day-Date, respectively introduced in 1945 and 1956, but also importantly for their sports watches, such as the Explorer, Submariner and GMT-Master launched in the mid-1950s.</p><p>One of its most famous models is the Cosmograph Daytona. Launched in 1963, these chronographs are without any doubt amongst the most iconic and coveted of all collectible wristwatches. Other key collectible models include their most complicated vintage watches, including references 8171 and 6062 with triple calendar and moon phase, "Jean Claude Killy" triple date chronograph models and the Submariner, including early "big-crown" models and military-issued variants.</p>
