Rolex Datejust White Rolesor — 44 Diamond Bezel Dark Grey Diamond Dial | Ref. 279384RBR

The Lady-Datejust 28 in White Rolesor — combining polished Oystersteel with 18ct white gold — achieves a refined bi-material aesthetic that has become one of Rolex's most sought-after configurations for the 28 mm case size. Reference 279384RBR presents an exceptionally jewelled specification: a 44-diamond bezel encircles the case, while the dark grey dial features diamond-set hour markers, producing a watch of considerable visual impact that remains proportionately elegant on the wrist. The Jubilee bracelet in matching Rolesor completes the composition with its hallmark five-link flow.

At its heart, the 279384RBR houses the Rolex Calibre 2236, a self-winding movement introduced in 2015 specifically for Rolex's 28 mm and 31 mm ladies' models. The 2236 is noteworthy for its Syloxi hairspring — a silicon spiral spring manufactured to exacting tolerances using photolithographic techniques — which provides enhanced resistance to magnetic fields, shocks, and temperature variations compared to traditional metallic hairsprings. With a power reserve of 55 hours and Superlative Chronometer certification, the movement delivers accuracy to -2/+2 seconds per day in conditions that approximate real-world wear.

The contrast between the sparkling 44-diamond bezel and the moody dark grey diamond dial is a deliberate design tension that gives reference 279384RBR its distinctive personality — glamorous without being ostentatious, dramatic without being heavy. The Datejust's instant-change date at 3 o'clock, read through a Cyclops lens that magnifies the date 2.5 times, remains as practical as ever. This watch is equally at home as a sophisticated daytime piece or a formal evening companion, its bi-metal Rolesor construction ensuring it transitions effortlessly between both roles.
