The 36 mm round case is crafted in 18K yellow gold and built around Rolex's Oyster architecture, featuring a monobloc middle case, solid case back, and screw-down winding crown protected by the Twinlock double waterproofness system. A fluted bezel frames scratch-resistant sapphire crystal with a Cyclops lens over the date, and the watch carries a water resistance rating of 100 metres / 330 feet.
The white mother-of-pearl dial is set with diamonds in 18 kt gold settings, with baguette-cut diamonds positioned at 6 and 9 o'clock — a striking complement to the diamond-set President bracelet in 18 kt yellow gold, secured by a concealed folding Crownclasp.
Power comes from the Calibre 3255, a perpetual mechanical self-winding movement from Manufacture Rolex, delivering a precision of -2/+2 seconds per day after casing and approximately 70 hours of power reserve. The oscillator features a paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers, and the movement holds Superlative Chronometer certification reflecting both COSC and Rolex's own post-casing standards.
