If rarity is the name of your game in Geneva auction season, I suggest you take a look in this direction. In the last few years, everyone and their capable brothers have put a replica Rolex Daytona on their wrists, and for good reason. It is an outstanding design with similarly epic history, despite its incredible predecessor. What the concept seems to have become better known is that the Pre-Daytonas had begun to rise, but those watches were still “ordinary” compared with the Rolex reference watches that were toothed into stopwatches. 
Production of Ref. 2508 can be categorized into two separate generations. Many people will mistakenly tell you that these generations are classified according to the size of the box, with the early examples being 37mm and the later examples 35mm. Although the second-generation examples were not produced in a larger context, smaller case examples also appeared in the first generation. With that in mind, the easiest way to determine the age of a watch is to focus on the timepiece, since the first generation of watches will have oval timepieces instead of the square ones on later models.
Applying this rule to the watch in question, you can identify it as a small example of the first generation. What sets it apart from many other items sold at auction in recent years is its black lacquered dial. In recent years, such watches have been few and far between. While the watch’s iconic design and pop-culture significance are worthy of praise, the relatively inexpensive replica watch is of excellent quality and reasonable price.
