The Rolex Lady-Datejust 31 is one of the most enduring expressions of feminine luxury in watchmaking. Introduced as an evolution of the original Datejust—the world's first self-winding waterproof chronometer wristwatch to display the date in a window—the Lady-Datejust carries that storied heritage into a refined 31 mm format perfectly scaled for a broad range of wrists. Reference 278383RBRWRJ represents the model at its most glamorous, pairing the robustness of Rolex's proprietary Oystersteel with the warmth of 18k yellow gold in a combination Rolex calls Rolesor.

At the heart of this reference's visual identity is the diamond-set bezel, which encircles the case with a continuous ring of brilliant-cut stones. Diamonds are selected and set in-house at Rolex to exacting standards, and their presence on reference 278383RBRWRJ elevates what is already a dressy sports-adjacent watch into genuine fine-jewelry territory. The white dial with Roman numeral indexes reinforces that classical sensibility, offering strong legibility while remaining unmistakably sophisticated.

The 31 mm Oyster case is water-resistant to 100 meters (330 feet), underscoring that decoration never comes at the expense of Rolex's signature durability. The Oyster case construction—with its screwed-down crown and case-back—provides a hermetic seal that protects the automatic movement within, making reference 278383RBRWRJ genuinely wearable across a wide range of daily activities, not merely a showcase piece reserved for special occasions.

The watch is presented on Rolex's celebrated five-link Jubilee bracelet, originally designed in 1945 alongside the first Datejust. Its slender, elegantly tapering links sit beautifully on the wrist and complement the two-tone yellow gold and steel case, creating a harmonious aesthetic from lug to clasp. The Jubilee bracelet has long been considered one of the most comfortable and refined metal bracelets in the industry, and its presence here reinforces the Lady-Datejust 31's position as a daily companion rather than a display object.

For collectors and first-time luxury watch buyers alike, the Rolex Lady-Datejust 31 in reference 278383RBRWRJ represents outstanding long-term value. Rolex's consistent global demand, the timeless two-tone Rolesor configuration, and the added desirability of the diamond bezel all contribute to a watch that holds its character—and its value—exceptionally well over time. Bizak & Co. is proud to offer this reference to discerning buyers; our team is available to answer questions, provide additional imagery, and guide you through a confident purchase. Reach out today and let us help you acquire this iconic Lady-Datejust 31.

1. What makes the Rolex Lady-Datejust 31 ref. 278383RBRWRJ special?
Reference 278383RBRWRJ combines Oystersteel and 18k yellow gold in Rolex's classic two-tone Rolesor configuration with a factory diamond-set bezel and a white Roman dial. This blend of horological heritage and in-house diamond craftsmanship makes it one of the most desirable 31 mm dress watches available. It carries the full prestige of the Datejust line in an unambiguously luxurious package.

2. What movement powers the Rolex Lady-Datejust 31 278383RBRWRJ?
The watch is powered by an automatic movement, consistent with Rolex's use of in-house self-winding calibers across the Datejust family. Rolex automatic movements are chronometer-certified and known for their precision, reliability, and low maintenance requirements. The self-winding rotor means the watch winds itself through normal wrist motion during everyday wear.

3. What is the case size of the Lady-Datejust 31?
The case measures 31 mm in diameter, placing it in Rolex's mid-size Datejust category—larger than the classic 28 mm Lady-Datejust but more refined and slender than the full-size 36 mm or 41 mm Datejust. The 31 mm size suits a wide range of wrists and is a popular choice for those seeking a watch that reads as elegantly sized rather than oversized.

Absolutely. The Oyster case of reference 278383RBRWRJ is water-resistant to 100 meters (330 feet), and the robust Oystersteel construction means this watch is built to withstand daily life. While the diamond bezel and yellow gold accents make it a natural choice for formal occasions, the Jubilee bracelet and Rolex's overall build quality make it equally appropriate for everyday wear.

5. What is the bezel and dial like on the 278383RBRWRJ?
The bezel is set with brilliant-cut diamonds, mounted in-house by Rolex to precise stone-setting standards, creating a continuous ring of brilliance around the case. The dial is white with Roman numeral hour markers, lending the watch a classic, legible aesthetic that pairs naturally with the glamour of the diamond bezel. Together they create a balanced look that is both eye-catching and elegant.

6. Is the Rolex Lady-Datejust 31 278383RBRWRJ a good buy and how can I purchase it from Bizak & Co.?
