A Sigma dial is a Rolex dial named for the letters printed at the bottom of the dial at the 6 o'clock position. Most Rolex dials are commonly marked with “T Swiss T,” under the 6 o'clock marker, however, a Sigma dial is marked “σ T SWISS T σ.” This signifies the use of gold components within the dial.
