Crafted in 18 kt Everose gold, the 28 mm Oyster case of this Lady-Datejust features a monobloc middle case, a screw-down case back, and a screw-down Twinlock winding crown for waterproofness to 100 metres / 330 feet. A scratch-resistant sapphire crystal with a Cyclops lens over the date keeps the dial legible at a glance, while the diamond-set bezel lends an unmistakable sense of occasion.
The chocolate dial is set with diamonds throughout, and the Roman IX numeral is rendered in 18 kt gold and further set with 8 diamonds — each stone secured in 18 kt gold settings. Inside, Rolex Caliber 2236 drives the display via a perpetual, mechanical, self-winding movement with bidirectional winding through a Perpetual rotor. The oscillator employs a Syloxi silicon hairspring with patented geometry and Paraflex shock absorbers, delivering precision of -2/+2 seconds per day after casing, with a power reserve of approximately 55 hours. The movement carries Superlative Chronometer certification, reflecting both COSC testing and Rolex's own post-casing standards.
The watch rides on a Jubilee bracelet of five-piece links in 18 kt Everose gold, fastened by a concealed folding Crownclasp. Reference 279135RBR-0002 brings together warm rose-gold tones, diamond embellishment, and the reliable date complication that has defined the Datejust collection for decades.
