Measuring 36 mm across, 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 Twinlock winding crown that together deliver waterproofness to 100 metres. The bezel is set with diamonds, and a scratch-resistant sapphire crystal with a Cyclops lens over the date window completes the case.
The dial presents white mother-of-pearl set with diamonds in 18 kt gold settings, with baguette-cut diamonds marking the 6 and 9 o'clock positions. Powering the watch is the Calibre 3255, a perpetual mechanical self-winding movement produced by Rolex, offering a precision rating of -2/+2 seconds per day after casing, approximately 70 hours of power reserve, and a paramagnetic blue Parachrom hairspring with Paraflex shock absorbers. It carries Superlative Chronometer certification, reflecting both COSC and Rolex's own post-casing standards.
The President bracelet in 18 kt white gold features semi-circular three-piece links and secures with a concealed folding Crownclasp, lending the watch the polished, formal presence the Day-Date has long been associated with.
