The Rolex Lady-Datejust is one of the most enduring icons in fine watchmaking, having established the template for the elegant, date-displaying women's watch when it was introduced in 1957 as the feminine counterpart to the original Datejust. Over the decades the Lady-Datejust has evolved through a series of case sizes, and the current 31mm format—sitting neatly between the 28mm and the full 36mm—has become a favourite for those who appreciate a watch with just enough presence. Reference 278343RBR represents one of the most richly specified versions of this model available today.

The 31mm Oyster case of reference 278343RBR is constructed in Rolex's proprietary Oystersteel, a 904L stainless steel alloy renowned for its exceptional corrosion resistance and mirror-like polish, paired with 18k yellow gold on the bezel, crown, and bracelet centre links. This two-tone Rolesor configuration has been a hallmark of luxury Rolex sports-dress watches for generations, and here it provides a warm, luminous contrast against the cool steel flanks of the case.

The dial is where reference 278343RBR truly distinguishes itself. The olive green ground is decorated with an intricate floral motif, a design that references Rolex's storied tradition of crafting dials as miniature works of art. The green hue shifts beautifully in different lighting conditions—appearing rich and jewel-like indoors and softly verdant in natural light—making this one of the most visually alive dials in the current Lady-Datejust collection. The yellow gold domed bezel is set with diamonds, adding brilliance and three-dimensional depth that frames the dial like a jeweller's setting.

Powering the watch is a Rolex-certified automatic movement, ensuring the precision and reliability that have made Rolex a benchmark in the industry. The Oyster bracelet, with its three-link design integrating polished centre links in yellow gold and brushed outer links in Oystersteel, is both secure and supremely comfortable, sitting flat against the wrist. The water resistance of 100 metres (330 feet) means this is a watch built to accompany an active lifestyle without compromise.

From a collector's and buyer's perspective, two-tone Lady-Datejust references with factory-diamond bezels and special dial variants such as the floral motif consistently command strong secondary market interest. The 278343RBR configuration is sought after precisely because it combines three desirable elements—the warm metal combination, the diamond bezel, and the distinctive green floral dial—in a single reference.
