Rolex Lady-Datejust Yellow Rolesor — White Roman Dial | Ref. 279173

Reference 279173 belongs to the Lady-Datejust 28 collection and presents the Yellow Rolesor specification — Oystersteel case body paired with 18 ct yellow gold bezel, crown, and Jubilee bracelet centre links — at its most classically resolved. The 28 mm case diameter, a format that Rolex has refined over successive generations of the Lady-Datejust, provides a proportional foundation suited to the fluted bezel that defines this reference. The vertical fluting of the 18 ct yellow gold bezel introduces a rhythmic visual cadence around the case edge, a detail that rewards close inspection with its precise machining geometry.

The white dial with Roman numeral hour markers evokes the formal tradition of the European dress watch while remaining unmistakably contemporary in its execution. Roman numerals, rendered in applied yellow gold on this reference, carry a heraldic weight that aligns naturally with the warm tones of the Yellow Rolesor construction. The Calibre 2236, with its Syloxi silicon hairspring, governs timekeeping to Superlative Chronometer standards with a 55-hour power reserve, representing a substantial engineering investment for a watch of this case diameter. The Paraflex shock absorber completes the mechanical protection suite.

Fitted to the Jubilee bracelet in matching Yellow Rolesor, reference 279173 closes with the Crownclasp, integrating safety and elegance in a discreet folding mechanism. This reference articulates the enduring formula of the Lady-Datejust with particular clarity: a case of immaculate proportion, a movement of certified precision, and an aesthetic vocabulary that draws directly from the finest traditions of the Geneva dress watch.
