Sized at 28mm, the Lady-Datejust 279384RBR-0014 is built on a White Rolesor case — Rolex's combination of Oystersteel and white gold — featuring a monobloc middle case, screw-down case back, and screw-down winding crown with Twinlock double waterproofness. The bezel is set with diamonds, while scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case. Water resistance reaches 100 metres / 330 feet.
The dark grey dial features Rolex's Chromalight display, offering long-lasting blue luminescence for legibility in low light. The Oystersteel Oyster bracelet is composed of three-piece solid links and fastens with a folding Oysterclasp equipped with an Easylink 5mm comfort extension link.
Powering the watch is the self-winding Calibre 2236, a Manufacture Rolex movement featuring a Syloxi silicon hairspring with patented geometry, Paraflex shock absorbers, bidirectional winding via a Perpetual rotor, approximately 55 hours of power reserve, and Superlative Chronometer certification — reflecting both COSC and Rolex's own post-casing standards.
