Rolex Dateust 1603 from 1971

Rolex Datejust 1603 – Serial 27172XX (Circa 1971)
36mm | Automatic | Folded Oyster Bracelet | Watch Only | 2-Year Warranty

The Rolex Datejust reference 1603 is a cornerstone in the history of Rolex design—combining everyday wearability with timeless aesthetics and robust mechanics. Offered here is a clean example with serial number 27172XX, dating the watch to approximately 1971.

At 36mm, the stainless steel case wears perfectly across a range of wrist sizes and remains faithful to the classic Datejust proportions that have endured for decades. The signature engine-turned bezel adds character and contrast to the polished case flanks, giving it a slightly more utilitarian edge compared to its fluted bezel counterparts.

Powering this piece is the venerable Rolex Caliber 1570—an automatic, chronometer-rated movement known for its durability and reliability. The dial retains its vintage charm, housed under a domed acrylic crystal with the classic Cyclops magnifier over the date window.

This 1603 is paired with its original folded-link Oyster bracelet, a correct-period piece that wears light yet solid on the wrist. Please note this is a “watch only” offering—no box or papers—but it is backed by a 2-year mechanical warranty for peace of mind.

The Rolex Datejust debuted in 1945 and was the first automatic wristwatch to feature a date window that changed automatically at midnight—setting the stage for virtually every modern date-equipped watch that followed. The 1603 variant, with its engine-turned bezel and understated execution, remains a favorite among collectors seeking an authentic, vintage Rolex experience without unnecessary flash.
