Measuring 28 mm, the Oyster case is constructed from White Rolesor, blending Oystersteel with white gold. A screw-down winding crown with Twinlock double waterproofness and a monobloc middle case contribute to water resistance rated to 100 metres / 330 feet, while a scratch-resistant sapphire crystal with Cyclops lens over the date completes the case.
The dark grey dial features Roman numeral hour markers and is driven by the Rolex Caliber 2236 — a perpetual, mechanical, self-winding movement with bidirectional winding via a Perpetual rotor, a Syloxi silicon hairspring with patented geometry, and Paraflex shock absorbers. The movement delivers a power reserve of approximately 55 hours and a precision of -2/+2 seconds per day after casing, and carries Superlative Chronometer certification reflecting both COSC and Rolex post-casing standards.
The Oystersteel Jubilee bracelet with five-piece links secures via a concealed folding Crownclasp, lending the Lady-Datejust its distinctively refined silhouette on the wrist.
