Rolex Datejust 28 White Rolesor — 44 Diamond Bezel Silver Roman | Ref. 279384RBR

Reference 279384RBR sits at the jewellery-intensive end of the Lady-Datejust 28 lineup, combining White Rolesor construction with a factory-set 44-diamond bezel and a silver dial bearing Roman numeral hour markers. The RBR suffix distinguishes this variant, which uses brilliant-cut round stones in the bezel channel to produce a fine, graduated sparkle that reads differently from the baguette-set Pearlmaster alternatives. Launched as part of Rolex's 2017 introduction of the 279 generation, this 28 mm reference succeeds the earlier 179 series with a fully updated movement and refined ergonomics.

Calibre 2236 powers this watch — Rolex's current standard for its 28 mm ladies' references. It incorporates a Syloxi silicon hairspring, providing exceptional antimagnetic and shock resistance in a compact architecture. The self-winding movement features the Perpetual rotor and offers approximately 55 hours of power reserve. The Oyster case in White Rolesor uses 18 ct white gold for the bezel setting and crown, while the steel case body underpins structural integrity. The Jubilee bracelet with its delicate five-piece links is fitted as standard, lending a refined, bracelet-like quality to the overall presentation.

For buyers considering the Lady-Datejust 28 in its current generation, the 279384RBR with diamond bezel and Roman dial represents a well-specified middle tier — above the plain-bezel variants but distinct from the fully gem-set Pearlmaster. Secondary market pricing for clean examples in original condition remains firm, and the diamond bezel warrants provenance scrutiny to confirm factory origin. It appeals most to wearers who want substantial jewellery content without departing from Rolex's core dress-watch identity.
