Rolex stainless steel ref. 6238, ca 1964 chronograph, Pre Daytona. Tachymeter calibrated to 1000 units, oyster bracelet. The reference 6238 is known as the “Pre-Daytona.” Historically, it is a very significant piece for Rolex, as it marked the adoption of a modern aesthetic in the early 1960s. The dial signature features only 2 short lines, "Rolex" up top and "Chronograph" below. The chronograph function has a tachymeter track as well, though smaller than on previous models and at the edge of the dial. This was the last step before that track was effectively removed from the dial and placed on an external bezel, marking the “founding” design of the Daytona. The sub dials are slightly recessed, and the indices are applied, with tritium luminescence. Importantly, the 6238 offers a comfortable size 36mm Oyster case (10mm thick), and the manually-wound Valjoux 72 movement. Both elements remained in place over the next 30 years. Approximately 1,900 (a very small production run) of this reference were made from early to mid-1960s. Serial # 1077678, made in 1964, fitted with steel oyster bracelet and service dial.
