Housed in a 36 mm platinum Oyster case featuring a monobloc middle, screw-down case back, and screw-down Twinlock winding crown, this Day-Date carries a diamond-set bezel and scratch-resistant sapphire crystal with a Cyclops lens over the date. The case is waterproof to 100 metres / 330 feet, combining robust engineering with precious materials throughout.
The turquoise dial is itself set with diamonds, while the hour markers are rendered in 18 kt gold set with 32 diamonds, and the Roman VI and IX numerals in 18 kt gold are further set with 24 diamonds — creating a dial of exceptional depth and brilliance. The platinum President bracelet, formed from semi-circular three-piece links, fastens via a concealed folding Crownclasp for a seamless profile on the wrist.
Power comes from the Calibre 3255 perpetual, mechanical, self-winding movement — a Manufacture Rolex calibre 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 a Perpetual rotor, and an approximately 70-hour power reserve round out the movement's specification.
