Rolex Lady-Datejust 31 31 mm 278273BMDJ Steel/Yellow Gold Black Mother of Pearl

The Rolex Lady-Datejust is one of the most enduring icons in fine watchmaking — the first waterproof wristwatch designed specifically for women when it debuted in 1957, and a standard-bearer of understated luxury ever since. The 31mm case size occupies the sweet spot in the Lady-Datejust lineup, offering a commanding yet refined wrist presence that suits a wide range of wrist sizes without sacrificing legibility or visual impact. Reference 278273BMDJ represents the Lady-Datejust 31 at its most glamorous, bringing together the brand's signature two-tone aesthetic with one of the most coveted dial materials in haute horlogerie.

The case and Jubilee bracelet of ref. 278273BMDJ are crafted in a combination of Oystersteel — Rolex's proprietary corrosion-resistant alloy — and 18k yellow gold. This pairing gives the watch a versatile warmth: the cool precision of steel grounds the design, while the yellow gold bezel and bracelet center links introduce a richness that elevates the piece into luxury jewelry territory. The result is a watch that transitions seamlessly from boardroom to evening event.

The dial is the true showpiece of this reference. Black mother-of-pearl, harvested from the iridescent inner shell of mollusks, exhibits a living, shifting play of color that photographs cannot fully capture. Against a dark base, the natural iridescence produces shimmering violet, green, and silver highlights depending on the light source, ensuring that no two glances at the dial look quite alike. The yellow gold fluted bezel frames this spectacle with a geometric, light-catching profile that has been part of the Datejust identity since the model's earliest years.

Beneath the dial, an automatic movement keeps the Lady-Datejust 31 accurate and self-winding through the motion of the wearer's wrist. Rolex rates this watch to 100 meters (330 feet) of water resistance, underscoring the robust Oyster case construction that protects the movement from dust, pressure, and moisture in everyday situations. The Jubilee bracelet — a five-piece link design that Rolex introduced alongside the original Datejust in 1945 — adds a supple, jewel-like drape to the wrist that complements the dressy character of this reference perfectly.
