Introduced during the 1960s, the Rolex Cosmograph was named following the fervor surrounding outer space travel. Later bearing the inscription Daytona, due to Rolex’s involvement with the celebrated International Speedway car race, the popularity of the chronograph soared throughout the years, leading it to become an icon and source of great fascination.

With the ending production of the reference 6238, the Cosmograph was subject to research in order to enhance its commercial appeal. It is around 1967 that the first chronographs, such as the present example, were provided with “exotic” dials bearing a new tridimensional graphic layout. Diverting from standard dials, the background of the outer fifths of a second division matched the subsidiary registers, both slightly sunken with regards to the central surface of the dial. Furthermore, square shaped hour indexes were applied instead of the common baton indexes.

Reference 6241 was introduced in 1965, and remained in production for 5 years only, discontinued in 1969. It is distinguished by a number of traits which make it one of the most appealing vintage Rolex references: it holds historical interest being the first time the combination of black bezel and pump pushers were seen on a Daytona, and the short production run renders it one of the rarest Daytona models produced by Rolex.
