Rolex Datejust Reference 1601 with blue sigma dial 2 tone from 1973

olex Datejust ref. 1601 – Blue Sigma Dial – 1973

There are Datejusts… and then there are those Datejusts.
This ref. 1601 is one of the latter. A beautifully preserved example featuring a deep blue sigma dial in outstanding condition — crisp printing, clean surface, and perfectly aged tritium plots. These blue dials are already scarce, but finding one this sharp is something else entirely.

The classic fluted yellow-gold bezel pairs effortlessly with the steel case, while the solid two-tone Jubilee bracelet completes the look exactly as Rolex intended in the early 1970s. Elegant, timeless, and unmistakably vintage Rolex — with the kind of dial that stops seasoned collectors mid-scroll.

A watch that doesn’t shout, but quietly commands respect.

Technical background
The Datejust 1601 is powered by the legendary Rolex cal. 1570, a chronometer-rated automatic movement known for its robustness and longevity. The presence of sigma markings indicates original white-gold hour markers, a detail prized by collectors. Serial number places this watch firmly in 1973, right in the sweet spot of vintage Rolex production.
