Cased in 18 kt Everose gold measuring 28 mm across, the Lady-Datejust 279135RBR-0016 features a monobloc middle case, screw-down case back, and a Twinlock double waterproofness winding crown. The bezel is set with diamonds, while scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case. Water resistance extends to 100 metres / 330 feet.
The chocolate dial is rendered with Roman numeral hour markers, offering a warm, richly toned face that pairs naturally with the Everose gold surroundings. The 18 kt Everose gold President bracelet — composed of semi-circular three-piece links — fastens via a concealed folding Crownclasp, lending the piece a refined, uninterrupted profile on the wrist.
Power comes from the Rolex Caliber 2236, a perpetual mechanical self-winding movement featuring a Syloxi silicon hairspring with patented geometry and Paraflex shock absorbers. Bidirectional winding via the Perpetual rotor provides approximately 55 hours of power reserve, and the movement is rated to a precision of -2/+2 seconds per day after casing, carrying Superlative Chronometer certification (COSC plus Rolex certification after casing).
