Crafted in 18 kt yellow gold, the 40 mm case of this Day-Date features a monobloc middle case, a screw-down case back, and a screw-down Twinlock winding crown that provides waterproofness to 100 metres. A scratch-resistant sapphire crystal with a Cyclops lens over the date sits above the bright black dial, while the bezel is fully set with diamonds for an unmistakably bold presence on the wrist.
The dial itself is set with 10 baguette-cut diamonds at the hour positions, complementing the overall stone-set aesthetic. The President bracelet — constructed with semi-circular three-piece links in 18 kt yellow gold — fastens via a concealed folding Crownclasp, completing the watch's cohesive precious-metal composition.
Inside runs the Rolex Calibre 3255, a perpetual, mechanical, self-winding movement with bidirectional winding via a Perpetual rotor and a power reserve of approximately 70 hours. A paramagnetic blue Parachrom hairspring and Paraflex shock absorbers contribute to its precision, rated at -2/+2 seconds per day after casing and certified as a Superlative Chronometer to COSC standards plus Rolex's own post-casing certification. Day and date are displayed instantaneously in dedicated apertures with a secure rapid-setting function.
