Rolex Lady-Datejust 28 White Rolesor — Silver Index Dial with Fluted Bezel | Ref. 279174

The Lady-Datejust 28 in reference 279174 distils the essential Datejust proposition into its most elegantly proportioned expression. At 28 mm, this case size has been the cornerstone of Rolex's ladies' collection since the Datejust's expansion across case diameters in the mid-twentieth century. White Rolesor — the pairing of Oystersteel with 18 ct white gold — gives the case a cool, platinum-adjacent aesthetic that aligns closely with the fluted bezel's mirror-polished gold facets, which serve a functional origin as a decorative evolution of the knurled grip once used to screw down early Oyster crowns.

Calibre 2236 animates this reference, a movement developed entirely in-house and featuring the Syloxi hairspring — a proprietary silicon component that eliminates the need for a traditional shock-absorber spring. Silicon's inherent non-magnetic and low-friction properties contribute to a stable rate performance across temperature and field variations. The silver index dial presents clean applied hour markers without supplementary gem-setting, offering a pure and restrained aesthetic that allows the fluted bezel to remain the focal point. The Jubilee bracelet in Rolesor completes the specification with matched two-tone articulation.

Reference 279174 occupies the accessible entry point within the White Rolesor Lady-Datejust family, positioned below the diamond-bezel and diamond-dial configurations. For the collector, this represents a factory-correct specification with broad appeal and high wearability. The 28 mm Datejust has demonstrated consistently strong residual values, supported by enduring demand from buyers seeking a Swiss luxury daily-wear piece of understated refinement.
