The Rolex reference 6238 is the last in a long series of Rolex chronographs that led up to the Daytona, and is known as the "Pre-Daytona". The reference 6238 was the last Rolex chronograph to feature the tachometer scale on the dial (versus on the bezel on the Daytonas). It was also the last Rolex chronograph to feature a one color dial, versus the contrasting color subdials on a Daytona. The 6238 was presented in Rolex catalogs between 1964 and 1967 only. The case number 10777XX dates production of this watch to 1964. The 6238 is one of the most collectable of all Rolex chronographs.
Original case is stainless steel with a diameter of 35mm and domed acrylic crystal. Original round pump style chronograph pushers and original screw-down crown, all operating perfectly. Another collectable aspect of the 6238 is that this is the last Rolex chronograph to have a smooth non-engraved bezel.
Original dial is silver, taking on a champagne patina, with non-contrasting silver subdials. The subdials are sunken and have concentric guilloche.
Original movement is the manual winding Rolex chronograph Caliber 72B with 17 jewels, adjusted in 3 positions, and has column wheel construction. The 12 o’clock chronograph register does not reset to its zero position, which is an easy fix for a watchmaker. Inside case back is engraved ‘6238’. Movement is clean and running.
Strap is new custom rustic leather with steel Rolex buckle.
Watch is guaranteed original and authentic and this is a final sale.
