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

The Rolex Datejust is widely regarded as the archetype of the classic dress-sport watch, a title it has held since 1945 when it debuted as the first self-winding wristwatch to display the date in a window on the dial. Across nearly eight decades, the Datejust has evolved through dozens of case sizes and material combinations while preserving its signature silhouette: the fluted or set bezel, the magnifying Cyclops lens over the date aperture, and the iconic Jubilee bracelet first introduced alongside the model itself. The 31mm Datejust occupies a coveted mid-size position that suits a wide range of wrists and wears beautifully as both an everyday watch and a special-occasion timepiece.

The reference 278384RBRSDJ represents the upper tier of the current Datejust 31 collection, combining the corrosion-resistant strength of Oystersteel—Rolex's proprietary 904L stainless steel alloy—with the luminous warmth of 18k white gold applied to the bezel mounting and fluted crown. The result is a two-tone composition that feels simultaneously sporty and luxurious, a balance Rolex has perfected over generations of watchmaking. At 31mm in diameter, the case strikes an ideal proportion: substantial enough to read with clarity and presence on the wrist, yet refined enough to slip beneath a tailored cuff.

The diamond-set bezel of the 278384RBRSDJ is one of its most defining features, with individually selected stones set with the exacting standards for which Rolex's gem-setting ateliers are celebrated. Complementing the bezel is the silver diamond dial, where diamonds replace the applied hour markers, intensifying the play of light across the watch face throughout the day. Together, the bezel and dial diamonds transform this Datejust 31 into something closer to jewellery than mere timekeeping instrument—without sacrificing a single element of legibility or daily wearability.

Beneath the case, a Rolex automatic movement drives the watch with the reliable, self-winding precision that collectors around the world trust. The Oyster case provides water resistance to 100 meters (330 feet), so this watch is far more than a display piece; it is built to accompany its wearer through life's full range of activities. The screw-down Oyster crown and solid case back ensure the movement is protected from the elements, a hallmark of Rolex's engineering philosophy that every watch should function as capably as it looks.

The five-link Jubilee bracelet is, arguably, the most elegant bracelet in the Rolex catalogue, and it remains the signature pairing for the Datejust. Its polished centre links and brushed outer links echo the mixed textures of the case itself, creating a coherent design language from dial to clasp. On the wrist, the Jubilee drapes with a suppleness that belies its solid metal construction, confirming why collectors consistently seek out this bracelet configuration when shopping for a Datejust 31 for sale.
