Crafted in 18kt Everose gold, the 28mm Oyster case of this Lady-Datejust features a monobloc middle case, screw-down case back, and a screw-down winding crown with Twinlock double waterproofness, delivering water resistance to 100 metres / 330 feet. The bezel is set with diamonds, while a scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case.
The diamond-paved dial is set with 291 diamonds, creating an uninterrupted field of brilliance across the entire surface. Powering the watch is the Caliber 2236, a perpetual, mechanical, self-winding movement manufactured by Rolex, offering a precision of -2/+2 seconds per day after casing, a power reserve of approximately 55 hours, bidirectional winding via a Perpetual rotor, and a Syloxi silicon hairspring with Paraflex shock absorbers. The movement carries Superlative Chronometer certification, reflecting COSC testing followed by Rolex's own certification after casing.
The President bracelet in 18kt Everose gold, distinguished by its semi-circular three-piece links, secures via a concealed folding Crownclasp for a seamless, refined silhouette on the wrist. Reference 279135RBR-0021 represents the Lady-Datejust at its most jewel-forward.
