Rolex Lady-Datejust 31 31 mm 278343RBROGFLOMDJ Steel/Yellow Gold/Diamonds Green Rolex Lady-Datejust 31 31 mm 278343RBROGFLOMDJ Steel/Yellow…

The Rolex Lady-Datejust is one of the most storied names in watchmaking, tracing its lineage to 1957 when Rolex introduced the first self-winding, waterproof, date-displaying watch sized for a woman's wrist. Over the decades the Lady-Datejust has evolved into a benchmark of understated luxury, and the 31mm case size sits at the sweet spot of the collection — substantial enough to read beautifully on the wrist yet perfectly proportioned for an elegant silhouette. Reference 278343RBROGFLOMDJ represents the model at its most expressive, combining materials, gem-setting, and dial artistry that few timepieces in any price category can match.

The 31mm case of reference 278343RBROGFLOMDJ is crafted in Rolex's proprietary Oystersteel — a 904L stainless steel alloy renowned for its exceptional corrosion resistance and mirror-bright polish — paired with 18k yellow gold on the bezel, crown, and bracelet center links. This two-tone aesthetic, often called Rolesor by Rolex, is one of the house's most beloved design signatures, offering the warmth of gold alongside the durability and cool luster of steel. Water resistance to 100 meters (330 feet) is secured by the screw-down Triplock crown, making this Lady-Datejust as capable as it is beautiful.

The olive green floral motif dial is the undisputed centerpiece of this reference. Rolex's dial artisans craft these motif dials with remarkable precision, using intricate floral patterns that catch light at shifting angles and give the watch a living, almost botanical quality. The olive green hue is both contemporary and timeless — rich enough to command attention, subtle enough to complement virtually any wardrobe. The yellow gold domed bezel set with brilliant-cut diamonds adds a further dimension of glamour, encircling the dial with a continuous arc of scintillating light.

Beneath the Oyster case an automatic movement powers the watch, delivering the reliable date complication that defines the Datejust name. Rolex's manufacture movements are celebrated for their precision, longevity, and ease of servicing, meaning a Lady-Datejust purchased today is engineered to perform across generations. The Jubilee bracelet — another Rolex invention, introduced alongside the original Datejust in 1945 — completes the package with its five-piece link construction and characteristic flexibility, draping the wrist with a fluidity that distinguishes it from any other bracelet in the catalog.

For collectors and first-time luxury watch buyers alike, the Lady-Datejust 31 in reference 278343RBROGFLOMDJ represents an exceptional opportunity. The combination of a gem-set diamond bezel, rare floral motif dial, and two-tone Rolesor construction places this reference among the most desirable in the current Lady-Datejust range. Its 31mm footprint means it reads elegantly on a wide range of wrist sizes, and its water resistance and automatic movement make it every bit as practical as it is ornamental.
