Rolex Lady-Datejust 31 31 mm 278383RBRDGDO Steel/Yellow Gold/Diamonds Grey

The Rolex Lady-Datejust is one of the most storied watches in the history of horology, descending from a lineage that traces back to 1957 when Rolex introduced the first purpose-built ladies' Datejust. The 31mm case size—positioned between the 28mm Lady-Datejust and the full 36mm Datejust—was formalized in the current generation to serve wearers who desire a slightly more assertive presence on the wrist without sacrificing the model's classically feminine proportions. Reference 278383RBRDGDO sits at the pinnacle of this family, combining the brand's renowned Oystersteel with 18k yellow gold in the configuration Rolex calls Rolesor, and dressing every detail in fine diamonds.

The 31mm Oyster case of the 278383RBRDGDO is quintessential Rolex engineering: the middle case, caseback, and crown all lock together to form the hermetically sealed Oyster case that is water resistant to 100 meters (330 feet). The Twinlock winding crown screws securely against the case, ensuring the movement is protected whether the watch is worn at the pool, in the rain, or through the demands of an active lifestyle. The polished and brushed surfaces of the Oystersteel and yellow gold case elements create a visual interplay that rewards close attention.

The bezel of the 278383RBRDGDO is set with brilliant-cut diamonds, a flourish that transforms what is already an elegant sports-dress watch into a genuinely jewellery-quality timepiece. The dark grey dial—cool, sophisticated, and distinctly contemporary—serves as a perfect counterpoint to the warmth of the 18k yellow gold hour markers and hands, and the brilliance of the diamond bezel draws the eye without overpowering the legibility that is a Rolex hallmark. Together, these elements produce a dial composition that transitions effortlessly from day to evening.

The watch is presented on Rolex's Oyster bracelet, one of the most recognized and trusted metal bracelets in watchmaking. Its three-piece link construction, finished in matching Oystersteel and yellow gold, sits flat and comfortable on the wrist and is secured by the Oysterclasp with an Easylink comfort extension system—allowing wearers to fine-tune the fit by approximately 5mm without tools. The bracelet's durability and daily wearability are among the practical reasons the Lady-Datejust has remained the choice of discerning women for decades. An automatic movement powers the 278383RBRDGDO, offering the convenience of self-winding operation suited to active daily wear.
