Reference 128349RBR-0008 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 for waterproofness to 100 metres. The bezel is set with diamonds, and a scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case.
The pink opal dial is itself set with diamonds, while the hour markers in 18 kt gold carry 32 diamonds and the Roman VI and IX numerals in 18 kt gold are set with 24 diamonds — a layering of stone and precious metal that defines the dial's character. The bracelet is the President in 18 kt white gold, its semi-circular three-piece links secured by a concealed folding Crownclasp.
Inside beats Calibre 3255, a perpetual mechanical self-winding movement from Manufacture Rolex, certified as a Superlative Chronometer to a precision of -2/+2 seconds per day after casing. The oscillator features a paramagnetic blue Parachrom hairspring with Paraflex shock absorbers, bidirectional winding via a Perpetual rotor, and a power reserve of approximately 70 hours. The movement displays the day and date in instantaneous apertures with secure rapid-setting and a stop-seconds function for precise time setting.
