Measuring 36 mm, the case is crafted from 18 kt white gold and built around Rolex's Oyster architecture: a monobloc middle case, screw-down case back, and screw-down winding crown secured by the Twinlock double waterproofness system, delivering water resistance to 100 metres. A scratch-resistant sapphire crystal with a Cyclops lens magnifies the date display, while the bezel itself is set with diamonds for a consistently luminous profile.
The dial is fully paved with diamonds and punctuated by 10 baguette-cut, rainbow-coloured sapphires serving as hour markers — a combination that turns timekeeping into an exercise in chromatic spectacle. Day and date both appear in dedicated apertures with instantaneous, secure rapid-setting, and a stop-seconds function allows for precise time adjustment.
Inside runs Calibre 3255, a perpetual mechanical self-winding movement bearing Manufacture Rolex origins. It features a paramagnetic blue Parachrom hairspring, high-performance Paraflex shock absorbers, bidirectional winding via a Perpetual rotor, a power reserve of approximately 70 hours, and Superlative Chronometer certification — reflecting both COSC standards and Rolex's own post-casing verification of -2/+2 seconds per day precision. The President bracelet in 18 kt white gold closes with a concealed folding Crownclasp.
