This 6265 Sigma Dial Daytona is in beautifully crisp condition! Early in production of the 6265/6263 waterproof Cosmographs Rolex were fitting these 'sigma' dials without the Daytona signature and the distinctive little σ markers either side of the "T Swiss T" designation. Rarer than the classic 'Big Red' dials that followed, these early members of Rolex's most iconic Daytona family are more and more sought out by savvy collectors.
