6239, Daytona, Double Swiss Underline, Steel ARS2 This example is entirely originalA ref. 6239 Double Swiss Underline, the very first Daytona variation ever made. At the time the Double Swiss Underline debuted, Rolex was calling this model the 'Le Mans'. Made for one year only, it is a collector's Daytona featuring a fully demarcated 275 bezel, 6238 caseback, ROW balance bridge, and extremely rare original handset. This is amongst the best examples documented to date.
