The Rolex reference 6238 is a turning point and a landmark in the Rolex Chronograph history. Produced for a short period from the beginning of the 1960s to 1967, it was the last Rolex chronograph to feature a smooth bezel with a graduated tachymeter scale on the dial but also a model that paved the way to the reference 6239. The latter was the first Cosmograph Daytona ever released by Rolex, with which it shares certain design elements such as the crown, the pushers, case and indexes. Thus the nickname “Pre-Daytona” given by collectors to reference 6238.

Interestingly, even though it is called the Pre-Daytona, ref. 6238 was produced in parallel to ref. 6239. However, while the Cosmograph Daytona always featured a two-tone dial with either black with silver subdials or vice versa, the ref. 6238 was offered only with a monochrome dial. These small details make a massive difference for collectors, making the Pre-Daytona a favorite amongst vintage Rolex aficionados and connoisseurs.

The matte black, or so-called "grené" finished dial, is particularly rare, as the majority of this reference was available with a silvered dial. The present dial is part of the second generation "grené" dials with silver printing. The "T SWISS T" found at the dial’s lower edge by 6 o’clock indicates that Tritium was used for the luminous hands and hour markers.

The collectability of "Pre-Daytona" models is on the rise, and the overall superbly preserved condition of the present watch, along with its ultimate rarity, makes it a definite must-have for the discerning collector.
