The Rolex Cosmograph reference 6238 is a so called “Pre Daytona”, and has a simple elegance that was lost to the more sporty appearance of the Daytona models. This chronograph is totally original and its production dates to 1964. The silver dial, like the watch, is versatile enough to be worn with everything from a suit to shorts and a tee shirt.
Original stainless steel case measures 36mm diameter by 13.5mm thick. Crystal is acrylic. Screw down crown is original and is operating smoothly. Round pump style chronograph pushers are original and are operating perfectly. Case condition is mint.
Original movement is the manual winding Rolex Caliber 72B with 17 jewels and column wheel construction. Movement is very clean and running well. All chronograph functions return to their respective zero positions perfectly. Inside case back is stamped ‘6238’. Serial number 1077XXX dates production of the watch to 1964.
Original dial is silver with sunburst brush finish and applied hour markers. Because of the watch’s age, the dial has taken on a very light champagne color patina. The subdials are black and the chronograph seconds hand is blued. The dial is in great condition, though some of the luminous dots are darkened and there is very light spotting in some areas. Despite these small issues, I would rate the dial as being in 98% condition.
Watch is on a new Italian crocodile strap with genuine vintage Rolex tang style buckle.
