Rolex Datejust ’Grey Sigma Dial – Steel & White Gold’ – Reference 1601 (1973)

Heritage Narrative

The Rolex Datejust 1601 is one of the most classic and collectible expressions of the 36 mm Datejust line. Produced throughout the 1960s and 1970s, the model blends everyday practicality with refined details, most famously its fluted white-gold bezel and robust Oyster construction.

This 1973 example stands out with its Grey Sigma dial — a configuration marked by the discreet “s T SWISS T s” signature at 6 o’clock, denoting the use of solid gold hour markers and hands. Sigma dials have become highly desirable among collectors for their subtle exclusivity and strong vintage character.

Paired with a plexiglass crystal and a steel Oyster bracelet, this Datejust carries the unmistakable warmth, charm, and dimensionality that defined Rolex’s early ‘70s output. The 36 mm size remains the perfect proportion for a dress-meets-everyday Rolex, and the 1601 represents one of the most iconic executions of the form.
