Rolex Datejust 31 31 mm 278384RBRSDO Steel/White Gold/Diamonds Silver

The Rolex Datejust is one of the most iconic and enduring watch designs in horological history, introduced in 1945 as the first self-winding wristwatch to display the date in a window on the dial. Over eight decades, the Datejust has evolved through generations of refinement while retaining its essential character: an immediately recognizable case, the signature date magnified by the Cyclops lens, and Rolex's relentless commitment to precision. The 31mm Datejust sits at the heart of the collection, perfectly sized for a wide range of wrists and widely regarded as one of the most versatile luxury watches available for sale today.

Reference 278384RBRSDO represents one of the most glamorous expressions of the Datejust 31 family. Constructed from a combination of Oystersteel—Rolex's proprietary 904L stainless steel prized for its exceptional corrosion resistance and mirror-like polish—and 18k white gold, the case achieves a two-tone sophistication that manages to feel simultaneously sporty and opulent. At 31mm in diameter the proportions are graceful and universally flattering, sitting elegantly on the wrist without overwhelming it.

The diamond-set bezel is the jewel in the crown of this reference, quite literally. Individual diamonds are set with expert precision around the bezel, catching the light from every angle and lending the watch an undeniable presence. Paired with the silver dial, the result is a luminous, cohesive aesthetic that transitions effortlessly from a boardroom setting to a formal evening occasion. The silver dial provides a clean, cool backdrop that allows the hour markers and Rolex's signature applied indices to read with outstanding clarity.

Powering the 278384RBRSDO is an automatic movement, delivering the reliable self-winding convenience that has defined Rolex sports and dress watches for generations. The watch is water resistant to 100 meters (330 feet) thanks to the Oyster case architecture—its twinlock screw-down crown and carefully engineered case back providing protection well beyond what a dress watch of this elegance might suggest. The Oyster bracelet, one of the most copied and celebrated bracelet designs in watchmaking, rounds out the package with a secure, comfortable fit and a refined aesthetic that complements the diamond and white gold elements perfectly.
