1973 Rolex Datejust (Ref. 1601) Blue Sigma "Patina" Dial

The Rolex Datejust is one of the most iconic and most beloved Rolex watches ever made, even though the Datejust was launched in 1945 it has remained a timeless classic and is instantly recognizable as an item of refined quality and functional design. The Datejust can be worn just as easily with a suit as it can be with jeans and a tee shirt.

This specific Rolex ref. 1601 from 1973 features a stunning blue "Sigma" dial with a lovely patina that both accentuates the vintage charm of the watch and makes it one-of-a-kind. This Datejust would make a great start for a new vintage collector or be a great addition to an expanding collection. We love the early Rolex Datejust for its simplicity and its classic sophistication. Perfectly worn in any setting from formal to casual.

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 exceptional case is in very crisp condition, showing minimal signs of previous polishing and extremely thick lugs that show defined geometry with gentle signs of use. The white gold fluted bezel is also crisp and exhibits minimal signs of use. The case back retains defined finishing like the case. The original Rolex 6251H rolled-link Jubilee bracelet with 55 end pieces retains 22 links that show moderate stretch for the style of bracelet and will fit up to a 7 1/2-inch wrist.


The original, unique, and truly stunning blue "pie-pan" Sigma sunburst dial is oozing with vintage charm. Though it is somewhat common for blue dials to show a subtle patina around the lume plots, this dial takes that patina a step further to make for a very attractive overall vintage aesthetic. The tritium lume plots have taken on a vivid yellow patina and all remain intact, though the 3 o'clock plot displays nominal degradation when inspected under U.V. light. The original tritium hands match the dial perfectly, under U.V. light inspection the minute hand exhibits some very minor lume loss and remains stable, the hour hand shows no degradation. 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.
