Rolex Lady-Datejust 31 31 mm 278341RBRWMDO Steel/Rose Gold/Diamonds White Mother of Pearl

The Rolex Lady-Datejust is one of the most enduring icons in watchmaking, tracing its lineage to 1957 when Rolex introduced a date-display wristwatch scaled specifically for women. Over the decades it has remained the definitive dress watch for those who demand Swiss precision alongside effortless elegance, and reference 278341RBR represents the model at its most glamorous — combining precious metal, diamonds, and a breathtaking dial into a single cohesive statement.

At 31 mm, the case of reference 278341RBR occupies the sweet spot between the 28 mm Lady-Datejust and the full 36 mm Datejust, offering a presence that reads confidently on most wrists without overwhelming a slender wrist. The case and Oyster bracelet are crafted in Oystersteel — Rolex's proprietary 904L stainless steel alloy, prized for its superior corrosion resistance and mirror-bright polish — while 18k Everose Gold accents on the bezel, crown, and bracelet center links provide a warm, rose-tinted contrast that never tarnishes thanks to Rolex's exclusive gold alloy formulation.

The dial is the undisputed centerpiece of this reference. White mother-of-pearl, quarried from natural shells, displays an organic iridescence that shifts in color under changing light — no two dials are identical, making each watch subtly one of a kind. The Everose Gold domed bezel set with diamonds frames that luminous canvas with a ring of brilliant-cut stones, intensifying the play of light and lending the watch an undeniable fine-jewelry quality that transitions seamlessly from boardroom to black-tie event.

Powering the Lady-Datejust 31 is a Rolex-certified automatic movement, built and regulated in-house to Superlative Chronometer standards — meaning it has been tested by Rolex to a precision of −2/+2 seconds per day after leaving the manufacture, a benchmark significantly tighter than the official COSC standard. Water resistance is rated to 100 metres (330 feet) thanks to the Oyster case architecture: a screw-down Triplock crown and a solid case back that together create a hermetically sealed environment protecting the movement from moisture and dust in virtually any everyday situation.
