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.

The Rolex 6251H rolled-link Jubilee bracelet with 55 end pieces is stamped 3/71 and retains 22 links that show only moderate stretch and will fit up to a 7 3/4-inch wrist.


The silver "pie-pan" sunburst "Sigma" dial is in virtually flawless condition, showing no damage and nominal aging. The tritium lume plots have aged to a charming creamy patina and exhibit no degradation when inspected under U.V. light. The original tritium hands match the dial perfectly with no degradation present under U.V. light inspection. The metallic date wheel is original with "open" 6's and 9's.


None. The watch is keeping time perfectly backed by a 1-year warranty on accurate timekeeping.
