Crafted from platinum, the 40 mm Oyster case of this Day-Date 40 features a fluted bezel, a monobloc middle case construction, and a screw-down case back and winding crown with Twinlock double waterproofness. The scratch-resistant sapphire crystal carries a Cyclops lens over the date window, and the watch is waterproof to 100 metres / 330 feet.
The dial is fully paved with diamonds and sapphires, set with 8 baguette-cut diamonds and 2 baguette-cut sapphires at the 6 and 9 o'clock positions. The platinum President bracelet, featuring semi-circular three-piece links, closes with a concealed folding Crownclasp for a seamless finish on the wrist.
Powering the watch is the Calibre 3255 — a perpetual, mechanical, self-winding movement from Manufacture Rolex, COSC certified to a precision of -2/+2 seconds per day after casing. It offers approximately 70 hours of power reserve, bidirectional winding via a Perpetual rotor, a paramagnetic blue Parachrom hairspring, and Paraflex shock absorbers, alongside instantaneous day and date displays with secure rapid-setting and stop-seconds functionality.
