Reference 128236-0017 houses a 36 mm Oyster case crafted entirely in platinum, featuring a fluted bezel, solid case back, and a screw-down winding crown equipped with the Twinlock double waterproofness system. A scratch-resistant sapphire crystal with a Cyclops lens over the date sits above the white dial, and the watch is waterproof to 100 metres / 330 feet.
The white dial is appointed with Roman numerals and pairs with a platinum President bracelet composed of semi-circular three-piece links, secured by a concealed folding Crownclasp. At the heart of the watch is the Rolex Calibre 3255, a perpetual mechanical self-winding movement offering a precision rating of -2/+2 seconds per day after casing and a power reserve of approximately 70 hours. The oscillator features a paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers, and the movement is COSC certified.
Functions include center hour, minute, and seconds hands alongside instantaneous day and date displays in dedicated apertures with secure rapid-setting, plus stop-seconds for precise time setting. Bidirectional winding is achieved via a Perpetual rotor.
