Reference 128349RBR-0046 presents the Day-Date 36 in a 36 mm Oyster case crafted from 18 kt white gold, featuring a monobloc middle case, screw-down case back, and a screw-down Twinlock winding crown that delivers waterproofness to 100 metres. The bezel is set with diamonds, while a scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case.
The white dial is dressed with Roman numeral hour markers and displays the day and date in separate apertures via an instantaneous, secure rapid-setting mechanism. Stop-seconds functionality allows for precise time setting, and the Calibre 3255 — a perpetual, mechanical, self-winding movement with a paramagnetic blue Parachrom hairspring and Paraflex shock absorbers — powers the watch with a precision rating of -2/+2 seconds per day after casing and approximately 70 hours of power reserve. The movement carries Superlative Chronometer certification, reflecting both COSC and Rolex's own post-casing standards.
The 18 kt white gold President bracelet, composed of semi-circular three-piece links, fastens with a concealed folding Crownclasp. This example is dated to 2024.
