Early releases and features
Serious Rolex watch buyers and fans will know that the Rolex Cosmograph was first released in 1960, with the model 6239. The subsequent release, 6241 came onto the market a year later with minor cosmetic differences. The first version had a bezel made from solid steel, whereas the latter release had an insert made from clear acrylic, fitted with a steel ring. Both were available with two dial options - a standard with silver or black registers and an 'exotic' option, with black, cream and white sub-dials. These features were notable for creating a notable contrast, which generally didn't feature in the design of other Rolex models.
