Housed in a 28 mm Oyster case crafted from 18 kt Everose gold, this Lady-Datejust features a monobloc middle case construction with a screw-down case back and screw-down Twinlock winding crown. The bezel is set with diamonds, while a scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case. Water resistance is rated to 100 metres / 330 feet.
The chocolate dial is paired with a self-winding Caliber 2236 movement, a Manufacture Rolex perpetual mechanical movement offering a power reserve of approximately 55 hours. The oscillator employs a Syloxi silicon hairspring with patented geometry alongside Paraflex shock absorbers, and the movement delivers a precision of -2/+2 seconds per day after casing. Functions include centre hour, minute, and seconds hands, an instantaneous date with rapid setting, and stop-seconds for precise time setting. The movement holds Superlative Chronometer certification, reflecting both COSC and Rolex's own post-casing standards.
The watch rides on an 18 kt Everose gold President bracelet composed of semi-circular three-piece links and secured by a concealed folding Crownclasp. Reference 279135RBR-0005 brings together the warmth of Everose gold, the depth of a chocolate dial, and the technical precision of Rolex's Caliber 2236 in a 28 mm package suited to the Lady-Datejust collection.
