Housed in a 36 mm Oyster case crafted from 18 kt yellow gold, the Day-Date 36 ref. 128348RBR-0042 features a bezel set with diamonds and a scratch-resistant sapphire crystal fitted with a Cyclops lens over the date. The monobloc middle case is secured by a screw-down case back and a screw-down Twinlock winding crown, delivering water resistance to 100 metres / 330 feet.
The white dial carries Roman numeral hour markers and presents the full day and date display in apertures — the hallmark complication that defines the Day-Date lineage. Beneath, the self-winding Calibre 3255 Manufacture Rolex movement runs on a Perpetual rotor with bidirectional winding, a paramagnetic blue Parachrom hairspring, high-performance Paraflex shock absorbers, and approximately 70 hours of power reserve. It holds Superlative Chronometer certification, reflecting COSC testing plus Rolex's own post-casing standard of -2/+2 sec/day.
The watch rides the President bracelet in 18 kt yellow gold, composed of semi-circular three-piece links and secured by a concealed folding Crownclasp. This example is dated 2023.
