The present Day-Date was manufactured during the fourth quarter of 1955 and therefore before the official launch which occurred in Basel in 1956. The big so-called ‘Millerighe’ fluted bezel, a distinguishing feature of the early examples, and the gorgeous bracelet complete this wonderful example.Rolex was still searching for a stylistic identity, therefore the dial shows the ‘Day-Date’ writing placed at 6 o’clock, which is printed in red as well as the date wheel. Early Day-Date models were fitted with a thicker case compared to the classic Datejust cases from the same period, and were more curved than those of the references that followed, which displayed squared slim lines. Moreover, these models were fitted with a ‘rounded’ screw-down case back, similar to the Ovettone version for improved water resistance. Exceptionally rare and historically important, the present Day-Date is offered in outstanding original condition.
