Rolex Lady-Datejust 31 31 mm 278381RBRWMDJ Steel/Rose Gold/Diamonds White Mother of Pearl

The Rolex Lady-Datejust is one of the most enduring icons in watchmaking history, introduced as the world's first self-winding waterproof wristwatch with a date complication scaled for the female wrist. Across decades and countless iterations, the Lady-Datejust has remained the definitive benchmark for elegance combined with precision — a watch worn by generations of women who refuse to choose between beauty and substance. Reference 278381RBRWMDJ represents the modern 31mm expression of this legacy, and it is among the most desirable configurations Rolex has ever produced.

At 31mm, the Oyster case occupies the ideal middle ground between the slender 28mm Lady-Datejust and the full-size 36mm Datejust, offering outstanding wrist presence without overwhelming a refined wrist. The case itself is constructed in Oystersteel — Rolex's proprietary 904L stainless steel renowned for its exceptional corrosion resistance and mirror-like polish — and paired with Everose gold, the brand's exclusive 18k rose-gold alloy formulated to resist fading over a lifetime of wear. This two-tone architecture gives the watch a warmth and dimension that pure steel or pure gold alone cannot achieve.

The white mother-of-pearl dial is the centerpiece of this reference. Sourced from natural shell, each mother-of-pearl dial is unique, shifting through iridescent whites, creams, and subtle pinks depending on the light — no two dials are identical. Diamond hour markers replace applied indices, adding a further layer of brilliance that catches the light from every angle. The combination of natural shell and set diamonds elevates the 278381RBRWMDJ firmly into fine-jewelry territory without sacrificing legibility.

Framing the dial is a diamond-set bezel, one of Rolex's most prized adornments. Carefully selected and set stones circle the full perimeter of the case, transforming the functional bezel into a continuous ring of light. Completing the ensemble is the iconic Jubilee bracelet — a five-piece link design introduced by Rolex in 1945 specifically for the Datejust — rendered here in the same Oystersteel and Everose gold combination as the case. The result is an unbroken flow of material and craftsmanship from lug to lug. The watch is rated to 100 meters of water resistance, courtesy of the screwed-down Triplock winding crown and the Oyster case construction.
