Rolex Lady-Datejust 31 31 mm 278273WMDO Steel/Yellow Gold White Mother of Pearl

The Rolex Lady-Datejust is one of the most enduring icons in watchmaking history, tracing its lineage to 1957 when Rolex introduced the world's first self-winding waterproof wristwatch with an automatically changing date for women. Across more than six decades the Lady-Datejust has remained the definitive expression of understated luxury at a feminine scale, and the contemporary 31mm generation continues that tradition with modern materials and refined proportions that sit beautifully on a range of wrist sizes.

Reference 278273WMDO belongs to the current-generation Lady-Datejust 31 collection, distinguishing itself through a two-tone combination of Oystersteel and 18k yellow gold. Oystersteel is Rolex's proprietary 904L stainless steel alloy, chosen for its exceptional corrosion resistance and the mirror-bright polish it sustains over decades of wear. Paired with 18k yellow gold on the bezel and crown, the result is a warm, luxurious contrast that rewards close inspection without ever feeling ostentatious.

The dial of the 278273WMDO is finished in white mother-of-pearl, a material harvested from the inner lining of mollusks whose structural color shifts subtly with every change in light. No two mother-of-pearl dials are identical, meaning each watch carries a one-of-a-kind chromatic signature. The 18k yellow gold fluted bezel frames this iridescent canvas perfectly, its precisely machined grooves catching light to create a scintillating crown around the dial.

Power comes from a Rolex-certified automatic movement, winding continuously through the natural motion of the wearer's wrist, eliminating the need for manual winding during regular use. The watch is water resistant to 100 meters (330 feet) thanks to the hermetically sealed Oyster case, the screw-down Twinlock crown, and the scratch-resistant sapphire crystal. Worn on the Oyster bracelet — Rolex's most recognizable three-link design — the 278273WMDO offers both security and a sleek, polished profile that transitions effortlessly from day to evening.

For collectors and first-time Rolex buyers alike, the Lady-Datejust 31 in reference 278273WMDO represents exceptional long-term value. Two-tone Rolex references with mother-of-pearl dials have demonstrated enduring desirability in the secondary market, and the 31mm case size occupies a versatile sweet spot between the 28mm and 36mm options. At Bizak and Co. this watch is offered as certified authentic and brand new, giving the buyer complete confidence in provenance and condition.
