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

The Rolex Datejust is widely recognized as the archetype of the classic watch—an icon that has graced the wrists of heads of state, artists, and tastemakers since its introduction in 1945. As the first self-winding waterproof watch to display the date in a window on the dial, the Datejust defined an entire category and has been refined across decades without ever losing its essential character. The Datejust 31 occupies a particularly cherished position within the family, offering a mid-size 31mm case that suits a wide range of wrist sizes while retaining every hallmark detail that defines the line.

Reference 278384RBRSSO presents the Datejust 31 in its most glamorous configuration. The case and Oyster bracelet are rendered in a distinguished combination of Oystersteel—Rolex's proprietary 904L stainless steel prized for its exceptional corrosion resistance and high polish—and 18k white gold, creating the luminous two-tone aesthetic that collectors associate with timeless luxury. The 31mm case diameter sits precisely between the brand's smaller Lady-Datejust and the full-size 36mm, making it a versatile choice for both dedicated women's watches and smaller-wristed collectors who appreciate proportion.

The dial of the 278384RBRSSO is finished in silver, a clean and classic choice that reflects light beautifully and ensures exceptional legibility. Index hour markers punctuate the dial with characteristic precision, and the overall composition is one of restrained sophistication. Crowning the case is the diamond-set bezel, which replaces the traditional fluted or smooth bezel with a continuous ring of brilliant-cut diamonds that add extraordinary sparkle and elevate this reference firmly into the realm of jewelry-grade watchmaking.

Powering the watch is a Rolex automatic movement, a self-winding caliber engineered and manufactured in-house to the stringent standards that have earned Rolex Superlative Chronometer certification. The movement winds itself through the motion of the wearer's wrist and delivers the smooth, reliable timekeeping performance that Rolex owners expect for a lifetime. With a water resistance of 100 meters (330 feet) courtesy of the iconic Oyster case and Twinlock crown, the 278384RBRSSO is not merely a dress watch—it is a fully capable everyday companion built to Rolex's exacting specifications.

The Oyster bracelet completes the package with the same blend of practicality and elegance that defines the watch as a whole. Its three-piece link construction flows naturally from the case and is secured by Rolex's fold-over Oysterclasp, offering security and ease of wear in equal measure. Whether worn to a formal occasion or as an elevated daily watch, this configuration harmonizes diamonds and steel in a way that feels both bold and effortlessly wearable.
