The Rolex Daytona, ref. 6265 in this post features a rare black Sigma dial with white subdials and a CRS marked caseback.

Most Daytona dials are marked with “T Swiss T,” however a Sigma dial is marked “σ T SWISS T σ.” These Daytona’s get the name from the two O shaped symbols on each side of the “T SWISS T.” Dials marked with this lettering are fitted with solid gold markers, unlike other dials which may use steel or other materials. Sigma dials come in both yellow and white gold and are very rare.
