Crafted in 18 kt yellow gold, this 31 mm round-case Datejust 31 features Rolex's Oyster architecture — a monobloc middle case, screw-down case back, and a screw-down Twinlock winding crown — delivering water resistance to 100 metres / 330 feet. Scratch-resistant sapphire crystal with a Cyclops lens magnifies the date window, while the bezel is set entirely with diamonds for a distinctly luminous presence on the wrist.
The dial in white mother-of-pearl is further adorned with diamonds set in 18 kt gold settings, and hour markers sit alongside centre hour, minute, and seconds hands. An instantaneous date complication with rapid setting and stop-seconds for precise time setting complete the dial's functionality. The Calibre 2236, a COSC-certified Manufacture Rolex movement, powers the watch with a perpetual, mechanical, self-winding action, a Syloxi silicon hairspring with patented geometry, Paraflex shock absorbers, and a power reserve of approximately 55 hours.
The President bracelet in 18 kt yellow gold, distinguished by its semi-circular three-piece links, secures via a concealed folding Crownclasp for a seamless profile. Reference 278288RBR-0006 represents a thoroughly jewelled interpretation of Rolex's enduring Datejust lineage.
