Rolex Datejust 31 mm 278240PNKRO Steel/White Gold/Diamonds Pink

The Rolex Datejust is, by any measure, the archetypal dress watch — a reference that has defined horological elegance since its debut in 1945 as the first self-winding wristwatch to display the date in a window on the dial. Across its many decades and iterations, the Datejust has remained a cornerstone of Rolex's catalog, evolving in size, material, and decoration while retaining the timeless silhouette and mechanical integrity that made it legendary. The 31 mm mid-size case bridges the gap between the classic Lady-Datejust and the full-size 36 mm and 41 mm references, offering a versatile wearing experience that suits a wide range of wrist sizes and style sensibilities.

Reference 278240PNKRO represents one of the most visually arresting expressions of the Datejust 31 available on the secondary market. The case and bracelet are rendered in a combination of stainless steel and white gold — a pairing that delivers the durability of Oystersteel alongside the luminous warmth of white gold accents. At 31 mm in diameter, the case strikes an ideal balance: substantial enough to read as a confident statement piece, yet refined enough to wear under a cuff or alongside delicate jewelry.

The pink Roman dial is the undeniable focal point of this reference. The blush tone carries a softness that reads as both romantic and sophisticated, while the Roman numerals lend a classical architectural quality that references the Datejust's long history as an instrument of formal timekeeping. Pink dials have surged in desirability among collectors and fashion-conscious buyers alike, and the Roman numeral variant in particular commands attention for its heritage-inflected character.

The custom diamond bezel elevates the 278240PNKRO into genuine jewelry-watch territory. Diamonds encircling the bezel catch and refract light with every movement of the wrist, amplifying the inherent brightness of the white gold elements and providing a sparkling frame for the warm pink dial behind them. The Oyster bracelet — one of Rolex's most enduring and technically accomplished link designs — closes the look with its characteristic three-link architecture, ensuring comfort, security, and a seamlessly integrated aesthetic from dial to clasp. Powering the watch is Rolex's automatic movement, delivering the reliable self-winding performance that generations of Datejust owners have come to depend upon, with a water resistance of 100 meters (330 feet) providing genuine everyday practicality.
