At 28mm, this Lady-Datejust is built around a monobloc middle case in White Rolesor, the signature Rolex combination of Oystersteel and white gold. The bezel is set with diamonds, while scratch-resistant sapphire crystal with a Cyclops lens over the date keeps the dial protected and highly readable. A screw-down case back and winding crown with Twinlock double waterproofness deliver water resistance to 100 metres / 330 feet.
The silver dial features a Chromalight display with long-lasting blue luminescence for legibility in low light. Powering the watch is Calibre 2236, a self-winding mechanical movement from Manufacture Rolex with a precision rating of -2/+2 seconds per day after casing, a power reserve of approximately 55 hours, and a Syloxi silicon hairspring with Paraflex shock absorbers. The movement holds Superlative Chronometer certification, reflecting both COSC testing and Rolex's own post-casing standards.
The Oystersteel Oyster bracelet is constructed from three-piece solid links and secured by a folding Oysterclasp with an Easylink 5mm comfort extension link, allowing for easy on-the-fly adjustment. Reference 279384RBR-0008 is a refined choice for those drawn to the enduring Lady-Datejust silhouette with added diamond detail.
