Rolex Lady-Datejust 31 31 mm 278341RBRWRJ Steel/Rose Gold/Diamonds White

The Rolex Lady-Datejust is one of the most enduring icons in watchmaking history, tracing its origins to 1957 when Rolex introduced the world's first self-winding, waterproof, and date-displaying watch scaled specifically for a woman's wrist. Over the decades, the Lady-Datejust has evolved through generations of refinement while preserving the hallmarks that made it legendary: the instantly recognizable case silhouette, the date window at three o'clock magnified by the Cyclops lens, and a breadth of material and dial combinations that allow every wearer to make it distinctly her own. Reference 278341RBRWRJ represents the current 31mm generation of this lineage, a size that strikes a confident balance between classic femininity and contemporary wrist presence.

The case of the 278341RBRWRJ is constructed in Rolex's proprietary Oystersteel, an alloy drawn from the 904L family of stainless steels renowned for its exceptional corrosion resistance and ability to take a mirror-like polish that lasts. Complementing the steel is 18k Everose gold, Rolex's exclusive rose gold alloy formulated with a precise addition of platinum to resist fading and maintain its warm blush tone across decades of wear. Together, the two materials create the two-tone aesthetic that has long been one of the most coveted configurations in the Datejust catalog, and they are joined here by a domed bezel set with a continuous parade of brilliant-cut diamonds that frame the dial with light-catching brilliance.

The white dial is the perfect canvas for this combination, offering clean legibility against the warmth of the Everose gold hour markers and hands. The Cyclops lens magnifies the date at three o'clock for effortless reading, a Rolex signature detail that is as functional as it is iconic. The Jubilee bracelet—invented by Rolex in 1945 specifically for the Datejust—completes the presentation with its five-piece link construction, lending a supple, jewel-like drape to the wrist that remains one of the most recognized bracelet designs in luxury watchmaking.

Beating at the heart of this Lady-Datejust 31 is an automatic movement, meaning the watch winds itself through the natural motion of the wearer's wrist and requires no battery. The Oyster case provides 100 meters (330 feet) of water resistance, making this a watch that can accompany its owner through daily life without the anxiety that often accompanies fine jewelry-adjacent timepieces. It is a genuine instrument as much as it is an adornment, built to Rolex's famously exacting tolerances.

For collectors and first-time buyers alike, the Lady-Datejust 31 in Oystersteel and Everose gold with a diamond bezel occupies a singular position: it is recognizable without being flashy, complex in its craftsmanship yet effortless in its appeal, and backed by one of the most robust secondary markets of any luxury watch brand in the world. Demand for diamond-bezel two-tone references consistently outpaces supply through authorized channels, making the secondary market an important and legitimate route to ownership.
