Rolex Datejust Yellow Rolesor — Silver Diamond Dial, Fluted Bezel | Ref. 279173

The 279173 is a Lady-Datejust 28 in Yellow Rolesor — Rolex's term for the combination of Oystersteel and 18-carat yellow gold, united most visibly in the fluted bezel and Jubilee bracelet centre links. At 28 mm, this is the smallest case diameter in the modern Datejust lineup, and its proportions speak directly to buyers seeking a refined, classically feminine watch rather than a scaled-down sport model. The fluted gold bezel is one of Datejust's most storied details, originally designed to tighten the caseback — a function long since superseded, but retained as a hallmark of identity.

The dial fitted here uses a silver ground set with diamond hour markers, creating a characteristic sparkle that reads as both dressy and versatile. Rolesor execution means the dial surround, bezel, and bracelet details are in 18-carat gold while the case and bracelet flanks remain in Oystersteel, blending durability with precious warmth. The Calibre 2236 — a movement developed specifically for the smaller Datejust and Pearlmaster cases — provides Rolex's Syloxi hairspring for superior shock and magnetic resistance within a compact architecture.

Buyers drawn to the 279173 typically value the balance of precious material presence and everyday wearability that Rolesor achieves. The factory diamond dial elevates the reference meaningfully above the plain-dial variants and sustains demand on the secondary market. For someone seeking a versatile watch that can transition from a business environment to a formal occasion without compromise, the Yellow Rolesor configuration in 28 mm remains a perennial choice within Rolex's ladies' collection.
