Rolex Lady-Datejust 31 31 mm 278383RBROGRDVIO Steel/Yellow Gold/Diamonds Green

The Rolex Lady-Datejust 31 is one of the most enduring icons in fine watchmaking, a model that has defined elegant precision on the wrist since Rolex introduced the Datejust family in 1945 — the first self-winding wristwatch to display the date in a window at 3 o'clock. The Lady-Datejust line refined that legacy for a smaller 31mm case, and over successive generations it has become the definitive dress-sport watch for the discerning collector who refuses to choose between luxury and durability. Reference 278383RBROGRDVIO represents the current generation of this storied lineage, combining the iconic Datejust silhouette with materials and finishing that push it firmly into fine-jewellery territory.

The 31mm Oyster case of reference 278383RBROGRDVIO is constructed in Rolex's proprietary Oystersteel — a 904L stainless steel alloy prized for its exceptional corrosion resistance and mirror-bright polish — complemented by 18k yellow gold on the bezel ring, winding crown, and Oyster bracelet center links. This two-tone Rolesor combination has been a Rolex hallmark for decades, and on this reference the warm gold tones play beautifully against the cool steel, giving the watch equal authority in a boardroom or at a candlelit dinner. The Oyster case is sealed to 100 meters (330 feet) of water resistance, a testament to the engineering integrity that underlies even the most ornate Rolex configurations.

The dial is the centerpiece of 278383RBROGRDVIO and the detail that makes this reference genuinely covetable. The deep olive-green surface is rendered with rich depth, and Roman numeral hour markers in yellow gold trace around it with classical refinement. The green dial trend has electrified the collector community across the past several years, and Rolex's execution on this Lady-Datejust is widely regarded as among the most harmonious expressions of that palette in the brand's catalog — the color flatters a wide range of skin tones and pairs naturally with the yellow gold accents. A date aperture framed by a cyclops lens at 3 o'clock completes the dial architecture with characteristic Rolex legibility.

Encircling the dial is the diamond-set bezel, in which individually hand-set brilliant-cut diamonds replace the traditional fluted or smooth bezel profile. The result is a halo of light that elevates the watch from accomplished timepiece to genuine jewel. The automatic movement beating within the Oyster case delivers the reliability and precision that have made Rolex the world's most recognized watch brand, driving the seconds, minutes, hours, and date display with the consistency collectors depend on. The Oyster bracelet — with its signature three-piece link construction and folding Crownclasp — ensures the watch sits securely and comfortably on the wrist while maintaining the polished aesthetic of the case and dial.

On the wrist, the Lady-Datejust 31 in reference 278383RBROGRDVIO occupies a sweet spot that larger sport watches cannot reach: substantial enough to read clearly and make a statement, yet proportioned to wear gracefully under a shirt cuff or alongside fine jewelry. The interplay of olive green, sparkling diamonds, and yellow gold makes this one of the most photographed and wished-for Datejust references in recent memory, and pre-owned examples in desirable configurations command strong secondary market attention.
