Reference 128235-0070 features a 36 mm Oyster case crafted from 18kt Everose gold, built around a monobloc middle case with a screw-down case back and screw-down Twinlock winding crown for water resistance to 100 metres. The fluted bezel frames a scratch-resistant sapphire crystal fitted with a Cyclops lens over the date aperture.
The white dial displays Roman numeral hour markers alongside instantaneous day and date readouts in dedicated apertures. Power comes from the Calibre 3255, a perpetual mechanical self-winding movement produced by Rolex that delivers a precision rating of -2/+2 seconds per day after casing. Its paramagnetic blue Parachrom hairspring and Paraflex shock absorbers contribute to the movement's robustness, while bidirectional winding via the Perpetual rotor provides approximately 70 hours of power reserve. The calibre carries Superlative Chronometer certification, reflecting both COSC standards and Rolex's own post-casing verification.
The watch rides on the President bracelet in 18kt Everose gold, secured by a concealed folding Crownclasp — a configuration that has long defined the Day-Date's standing as one of watchmaking's most recognized references.
