Rolex Lady-Datejust 28 White Rolesor — Dark Grey Roman Dial, 44-Diamond Bezel | Ref. 279384RBR (2)

The Rolex Lady-Datejust 28 ref. 279384RBR in White Rolesor presents one of the most elegantly composed contrasts in the current Rolex catalogue. White Rolesor — combining Oystersteel with 18-carat white gold on the bezel, crown, and Jubilee bracelet centre links — creates a seamlessly cool, silver-toned aesthetic that frames a dark grey dial of considerable sophistication. Roman numerals at each hour position impart a classical legibility, their vertical strokes and serifs evoking the heritage of pocket-watch and dress-watch traditions carried into the twenty-first century. The 44-diamond-set bezel, each stone calibrated and individually claw-set, elevates the piece into the domain of fine jewellery while retaining the structural integrity of an Oyster case rated to 100 metres.

Powering the ref. 279384RBR is Rolex's Calibre 2236, the most advanced ladies' movement the manufacture has produced. The 2236's Syloxi silicon hairspring — developed in collaboration with Rolex's materials science division — confers immunity to magnetic interference, improved isochronism across a wide power-reserve range, and long-term dimensional stability. The movement's 55-hour power reserve and 55 jewel count represent substantive upgrades over its predecessor, the 2235, and position the Lady-Datejust 28 as a technically serious instrument rather than merely an accessory.

For the seasoned collector, the RBR suffix denotes the Rain Bow Rainbow bezel or diamond-set variant — a configuration that has commanded consistent auction strength. Dark grey dials with Roman numerals thread a needle between formal gravity and decorative appeal, attracting buyers who seek versatility across formal and semi-formal occasions. The 279384RBR with this dial specification is a considered choice for the collector building a wardrobe of watches that span dressing contexts without redundancy.
