Rolex Lady-Datejust 28 Yellow Gold — Diamond Paved Roman Dial with Fluted Bezel | Ref. 279178

The Lady-Datejust 28 reference 279178 in 18 ct yellow gold exemplifies Rolex's jewellery watchmaking at its most refined. The dial presents a diamond-pavé ground set with Roman numeral hour markers, a combination that references the great tradition of dress watchmaking while remaining unmistakably contemporary in its execution. Against the warm lustre of yellow gold — carried through in the case, fluted bezel, and bracelet — the pavé-set diamonds create a surface of continuous brilliance, each stone calibrated for colour and clarity against its neighbours.

The Calibre 2236 automatic movement, beating at the heart of this reference, was developed specifically for Lady-Datejust and smaller Datejust models and incorporates a silicon Syloxi hairspring as a centrepiece of its construction. The Syloxi, produced using LIGA microfabrication technology, is immune to magnetic fields and does not require lubrication across its operational life, contributing to the movement's long-term accuracy and reduced service intervals. Certified as a Superlative Chronometer, the 2236 is regulated to -2/+2 seconds per day after assembly within the Oyster case.

For collectors focusing on Rolex's precious ladies' references, the 279178 with a diamond-pavé Roman dial occupies a particularly desirable position. Yellow gold Lady-Datejust references with fully gem-set dials are among the most visually commanding pieces in the current Rolex ladies' catalogue, and the Roman numeral configuration adds a classical legibility that distinguishes this dial variant from simpler index-set alternatives. Provenance — especially original box and papers — meaningfully affects both aesthetic satisfaction and future value when placing this reference within a broader collection.
