The "DNA" of the Oyster Cosmograph is well-known to collectors and scholars today. While the model features a multitude of subtle dial variations, such as the placement of the "Daytona" signature, or the font size of "Rolex", the market acknowledges that a non-"Paul Newman" stainless steel reference 6263 and 6265 should generally feature a black or silvered dial, with three subsidiary registers featuring concentric circles of various sizes and textures, depending on the year of production of the watch.

Yet, often examples appear and are so different, that they stun even the most "purist" scholar. The present watch is definitely such an example. Known as the "super flat", there is no "step" between the registers and the dial - a detail that is so characteristic of the Cosmograph Daytona. To add another element of intrigue, the dial does not feature the typical concentric circles in the subsidiary registers commonly found on reference 6263 or 6265.

While the market has identified some examples featuring only a slight "step" between the subsidiary registers, the so-called "semi-flat", examples with no step at all are exceedingly rare. Research concludes that the present watch is among no more than a handful of examples that have surfaced on the market thus far, each time fetching premiums in contrast to the regular Cosmograph Daytonas.

Rarer still, this watch is accompanied by its original guarantee, stating the watch was retailed in Argentina, providing another element to delight the stringent scholar.
