Housed in a 28 mm Oyster case crafted from Yellow Rolesor, this Lady-Datejust features a monobloc middle case, screw-down case back, and a screw-down winding crown with Rolex's Twinlock double waterproofness system, offering water resistance to 100 metres / 330 feet. A domed bezel frames the scratch-resistant sapphire crystal, which incorporates a Cyclops lens positioned over the date window for easy reading.
The silver dial is set with diamonds throughout, while the Roman IX marker is rendered in 18 kt gold and further accented with eight individual diamonds. The matching Yellow Rolesor Oyster bracelet is composed of three-piece solid links and fastens via a folding Oysterclasp fitted with an Easylink 5 mm comfort extension link.
Powering the watch is the Rolex Caliber 2236, a perpetual, mechanical, self-winding movement with bidirectional winding via a Perpetual rotor. It features a Syloxi silicon hairspring with patented geometry, Paraflex shock absorbers, an instantaneous date with rapid setting, stop-seconds for precise time-setting, and a power reserve of approximately 55 hours. The caliber carries Superlative Chronometer certification — meeting both COSC standards and Rolex's own post-casing criteria — with a precision of -2/+2 seconds per day.
