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

The Rolex Lady-Datejust 31 is one of the most enduring icons in Swiss watchmaking, tracing its lineage back to 1957 when Rolex introduced the first Datejust scaled for the feminine wrist. Over decades the model has evolved in proportion and sophistication, and today's 31mm case size — reference 278383RBR — sits squarely at the intersection of the brand's classic proportions and modern luxury. As one of the most recognized women's watches in the world, the Lady-Datejust continues to set the standard by which all other dress watches are measured.

Reference 278383RBR is distinguished by its combination of Oystersteel and 18k yellow gold, a pairing Rolex calls Rolesor. The warm glow of yellow gold appears on the bezel, crown, and Jubilee bracelet center links, contrasting beautifully against the polished steel case flanks and outer bracelet links. This two-tone aesthetic has been a hallmark of Rolex's most desirable configurations since the mid-twentieth century, and the 31mm diameter ensures the watch reads with presence on the wrist without overwhelming a slender or medium-sized wrist.

The dark grey dial adds a layer of contemporary sophistication that sets this reference apart from lighter-dialed variants. Grey dials have surged in popularity among collectors and enthusiasts for their versatility — equally at home with monochrome evening wear or casual daytime attire — and on the 278383RBR the depth of the dark grey creates a dramatic backdrop for the hour markers and hands. The diamond-set bezel encircling the dial adds brilliance, with individually set stones catching light from every angle and reinforcing the luxurious character of the reference.

The Jubilee bracelet, exclusive to the Datejust family, is one of Rolex's most celebrated bracelet designs. Its five-piece link construction creates an extraordinarily supple, fluid drape around the wrist, and on the 278383RBR the bracelet's alternating polished and satin-finished links echo the two-tone Rolesor theme of the case. The Oysterlock folding clasp provides security and includes Rolex's Easylink comfort extension system, allowing the wearer to fine-tune the fit with ease. Driving the watch is an automatic movement that keeps time with the precision and reliability synonymous with the Rolex name, and the watch carries a 100-meter water resistance rating for everyday confidence.
