Measuring 36 mm across, the Oyster case is crafted from 18 kt yellow gold and features a bezel set with diamonds, a screw-down winding crown with Twinlock double waterproofness, and a scratch-resistant sapphire crystal with a Cyclops lens over the date. The monobloc middle case and screw-down case back provide water resistance to 100 metres / 330 feet.
The chocolate dial is itself set with diamonds in 18 kt gold settings, with baguette-cut diamonds positioned at 6 and 9 o'clock for added depth and contrast. Day and date displays appear in apertures on the dial, complemented by centre hour, minute, and seconds hands with a stop-seconds function for precise time setting.
Inside runs the Calibre 3255, a perpetual mechanical self-winding movement from Manufacture Rolex, rated to a precision of -2/+2 seconds per day after casing and holding a power reserve of approximately 70 hours. The oscillator features a paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers. The watch is worn on an 18 kt yellow gold President bracelet with semi-circular three-piece links and a concealed folding Crownclasp.
