Rolex Lady-Datejust 31 31 mm 278383RBRCSJ Steel/Yellow Gold/Diamonds Champagne

The Rolex Lady-Datejust is the quintessential women's dress watch — a line that has graced the wrists of influential women since the 1950s and remains the standard by which all luxury ladies' timepieces are measured. The 31 mm case size occupies the ideal middle ground between the more petite 28 mm and the larger Datejust 36, offering generous dial legibility without sacrificing the delicacy that defines fine jewelry watches. Reference 278383RBRCSJ represents the fully dressed expression of this storied collection, bringing together precious materials, brilliant diamonds, and Rolex's legendary mechanical precision in a single cohesive package.

The case of the 278383RBRCSJ is constructed in a harmonious combination of Oystersteel — Rolex's proprietary 904L stainless steel, renowned for its exceptional corrosion resistance and mirror-bright polish — and 18k yellow gold. This two-tone pairing, known in Rolex terminology as Rolesor, has been a cornerstone of the Datejust identity for decades. It delivers the warm luminosity of gold alongside the durability and value retention of steel, making it equally at home at a formal dinner or a weekend brunch.

The champagne dial is one of the most coveted configurations in the Lady-Datejust lineup. Its warm, golden-toned surface catches light in a way that feels simultaneously subtle and opulent, providing the perfect canvas for the sparkling diamond index markers. The crowning detail, however, is the diamond-set bezel, which encircles the dial with a continuous row of brilliant-cut diamonds, elevating this reference well beyond a conventional timepiece and into the realm of fine jewelry. The combination of champagne, gold, and diamonds creates a colour palette of remarkable coherence.

At the heart of this watch beats an automatic mechanical movement, reflecting Rolex's long-standing commitment to in-house horological mastery. Rolex self-winding movements are celebrated for their precision, robustness, and low-maintenance reliability — qualities that ensure this Lady-Datejust will perform faithfully for decades with proper servicing. The Oyster case also provides 100 metres (330 feet) of water resistance, a practical assurance that speaks to the rugged engineering underpinning even this most glamorous of models.

The Jubilee bracelet, introduced by Rolex on the very first Datejust in 1945, is the definitive accompaniment to this reference. Its five-piece link construction drapes elegantly across the wrist, and in two-tone Rolesor it mirrors the case's interplay of steel and yellow gold. The Jubilee is widely regarded as one of the most comfortable and visually harmonious bracelets Rolex has ever produced, and its presence here reinforces the 278383RBRCSJ's credentials as a true collector's piece.
