Housed in a 28 mm Oyster case crafted from 18 kt Everose gold, this Lady-Datejust presents a chocolate dial dressed with Roman numerals and framed by a bezel set with diamonds. The monobloc middle case features a screw-down case back and a screw-down Twinlock winding crown, delivering water resistance to 100 metres / 330 feet. A scratch-resistant sapphire crystal with a Cyclops lens magnifies the instantaneous date display.
The warm tones of the dial carry through to the five-piece link Jubilee bracelet, also rendered in 18 kt Everose gold and secured by a concealed folding Crownclasp. Inside beats Rolex Caliber 2236 — a perpetual, mechanical, self-winding movement with a Syloxi silicon hairspring of patented geometry and Paraflex shock absorbers. Bidirectional winding via the Perpetual rotor provides approximately 55 hours of power reserve, and the movement achieves a precision of -2/+2 seconds per day after casing.
The caliber carries Superlative Chronometer status, reflecting both COSC certification and Rolex's own post-casing verification. Functions include centre hour, minute, and seconds hands, an instantaneous date with rapid setting, and a stop-seconds mechanism for precise time adjustment. Reference 279135RBR-0012 represents the Lady-Datejust at its most distinctive, combining horological capability with a warm, jewel-accented aesthetic.
