Rolex Lady-Datejust 28 28 mm 279173MDJ Steel/Yellow Gold White Mother of Pearl

The Rolex Lady-Datejust has been the definitive expression of refined femininity in Swiss watchmaking since the Datejust family was first introduced in 1945, and the modern 28mm generation — launched in 2016 — brought the collection fully in line with contemporary proportions and movement architecture. Reference 279173MDJ sits at the pinnacle of this lineage, combining two of the most desirable aesthetic choices available in the 28mm family: the yellow gold fluted bezel and the white mother-of-pearl diamond dial. For collectors and first-time luxury watch buyers alike, the 279173MDJ represents a timelessly correct configuration that has consistently held its desirability on the secondary market.

The case of the 279173MDJ measures 28mm in diameter and is constructed from Rolex's proprietary Oystersteel — a 904L stainless steel alloy prized for its exceptional corrosion resistance and mirror-like polish — paired with 18k yellow gold on the bezel and bracelet center links. This two-tone combination, sometimes called Rolesor by Rolex, gives the watch a warm, jewelry-forward character without sacrificing the durability that defines the Oyster case. The crown screws down securely to deliver 100 meters (330 feet) of water resistance, a practical specification that elevates the Lady-Datejust well beyond purely decorative timepieces.

The dial is the undisputed centerpiece of this reference. White mother-of-pearl is prized for its organic iridescence — no two dials are identical, as the natural nacre shifts through soft blues, pinks, and creams depending on the angle of light. Diamond hour markers are set around the chapter ring, adding brilliance that catches the light without overwhelming the delicate shimmer of the mother-of-pearl ground. The date aperture sits at three o'clock beneath a cyclops lens that magnifies the date 2.5 times, the hallmark detail that defines every Datejust since 1945.

Powering the 279173MDJ is Rolex's automatic movement, regulated to Superlative Chronometer standards and certified by COSC before receiving additional in-house testing. This movement is self-winding via a Perpetual rotor, meaning everyday wear keeps the watch running without manual intervention. The precision and reliability built into every Rolex movement means this Lady-Datejust can be worn as a daily companion for decades, requiring only periodic servicing to maintain factory performance.

On the wrist, the 28mm Jubilee-bracelet configuration is a study in proportion. The five-piece-link Jubilee bracelet — introduced alongside the original Datejust in 1945 — wraps elegantly around smaller wrists, its polished and satin-finished links echoing the two-tone theme of the case. The result is a watch that reads as a complete jewel-like object, yet wears with the confidence and dependability of a Rolex sports watch.
