Presented in a 40mm Oyster case crafted from 18kt Everose gold, this Day-Date 40 carries a bezel set with diamonds and a screw-down case back and winding crown. The Twinlock double waterproofness system and scratch-resistant sapphire crystal with Cyclops lens over the date round out the case construction, while water resistance extends to 100 metres / 330 feet.
The Eisenkiesel dial is itself set with diamonds, with 10 baguette-cut diamonds serving as hour markers. Day and date displays appear in apertures with secure rapid-setting, and a stop-seconds function allows for exact time setting. The President bracelet, composed of semi-circular three-piece links in 18kt Everose gold, fastens via a concealed folding Crownclasp.
Inside runs the Calibre 3255 perpetual mechanical self-winding movement, a Manufacture Rolex calibre rated to a precision of -2/+2 seconds per day after casing and holding a power reserve of approximately 70 hours. Bidirectional winding is achieved via a Perpetual rotor, and the oscillator incorporates a paramagnetic blue Parachrom hairspring alongside high-performance Paraflex shock absorbers. The movement carries Superlative Chronometer certification, reflecting both COSC and Rolex's own post-casing standards. Production year: 2023.
