This beautifull condition Daytona is a 4.1 million serial number case, hence bearing the so called “sigma” dial (seen from 3.5M to about 5M), due two the small characters before and after the T SWISS T at the bottom, below the six o’clock marker. The “sigma” is actually the logo of the Aprior, an association for the promotion of industrial use of gold, active in Switzerland. The logo would be displayed on cases and bracelets too, if made of gold, and would guarantee the highest standards of manufacturing quality. When visible on the dial, it meant the dial itself would be made out of a gold sheet, or that the hour markers therein applied were in solid gold. The Aprior logo was used in Switzerland from 1971 through 1995. This said, back to the watch: matching its overall quality level, the bezel and the pushers - also perfect - are absolutely consistent with the year of production. This great Daytona comes with its original punched papers and service records.

Birth of a Horological Icon Timepiece  The myth around the iconic Rolex Daytona has spread around the world recent years. Always has the Daytona model been attached to motor racing, at first Rolex called their new Cosmograph the “Le Mans” and little later to “Daytona” when Rolex started to sponsor the well known U.S. speedway.
Cosmograph: a name that was to be the forerunner of great fortune. Actually, the choice of the name proved to be neither easy nor expected. Whilst Rolex on the one hand flirted with the car-racing world, on the other hand it could not remain unaware of the vast media attention, which at that time was surrounding the conquest of outer space.
