Rolex Lady-Datejust 28 Yellow Gold — Champagne Roman Diamond Bezel President | Ref. 279138RBR

The Lady-Datejust 28 Ref. 279138RBR distils Rolex's vision of feminine luxury into 28 mm of 18 ct yellow gold, gem-setting expertise, and manufacture horological precision. The bezel is set with 44 brilliant-cut diamonds in a continuous pavé arrangement, providing a dazzling frame for the champagne dial with its Roman numeral hour markers — a combination that evokes the classical tradition of dress watchmaking while remaining unmistakably modern in its proportions. The President bracelet, reserved exclusively for Rolex's precious-metal references, completes an ensemble of quietly authoritative elegance.

Inside, the Calibre 2236 self-winding movement operates with a Syloxi silicon hairspring — a material that improves thermal stability and magnetic resistance compared to conventional alloys — and delivers a power reserve of approximately 55 hours. Rolex certifies every movement to the standards of a Superlative Chronometer: tested, adjusted, and verified in-house to a precision of -2/+2 seconds per day after casing. The screw-down Twinlock crown ensures the case achieves 100 metres of water resistance despite its jewellery-oriented design.

This variant, denoted by the RBR suffix indicating a diamond-set bezel, represents the full-luxury expression of the Lady-Datejust 28. The champagne Roman dial and yellow gold President bracelet speak a consistent aesthetic language throughout, making the 279138RBR one of the most cohesive and covetable references in the current Lady-Datejust collection. It is, quite simply, a masterclass in the art of the dress watch.
