Reference 128235-0068 presents the Day-Date 36 in an Oyster case crafted from 18 kt Everose gold, measuring 36 mm across. The fluted bezel frames a scratch-resistant sapphire crystal fitted with a Cyclops lens over the date aperture, while the screw-down crown employs a Twinlock double waterproofness system for water resistance to 100 metres.
The green aventurine dial is set with diamonds throughout: hour markers in 18 kt gold carry 32 diamonds, and the Roman VI and IX numerals in 18 kt gold are adorned with a further 24 diamonds, creating a richly detailed face. The President bracelet — composed of semi-circular three-piece links in 18 kt Everose gold — secures via a concealed folding Crownclasp.
Inside beats the perpetual, mechanical, self-winding Calibre 3255, a Manufacture Rolex movement certified as a Superlative Chronometer to a precision of -2/+2 seconds per day after casing. A paramagnetic blue Parachrom hairspring, high-performance Paraflex shock absorbers, bidirectional winding via Perpetual rotor, and an approximately 70-hour power reserve complete this timepiece's technical profile.
