At 28mm, this Lady-Datejust wears the Oyster case architecture in White Rolesor, Rolex's combination of Oystersteel and white gold. The monobloc middle case is fitted with a screw-down case back and screw-down Twinlock winding crown, delivering waterproofness to 100 metres / 330 feet. A scratch-resistant sapphire crystal with a Cyclops lens over the date sits above the white dial, which is dressed with Roman numeral hour markers.
The Oyster bracelet is constructed from three-piece solid Oystersteel links and secured by a folding Oysterclasp with an Easylink 5mm comfort extension link. The fluted white gold bezel completes the two-tone presentation, offering a refined contrast against the steel bracelet.
Powering the watch is the Caliber 2236, a perpetual mechanical self-winding movement from Manufacture Rolex. It features a Syloxi silicon hairspring with patented geometry, Paraflex shock absorbers, bidirectional winding via a Perpetual rotor, a power reserve of approximately 55 hours, and a precision rating of -2/+2 seconds per day after casing. The movement holds Superlative Chronometer certification, reflecting both COSC testing and Rolex's own post-casing standards.
