Housed in a 36 mm monobloc middle case crafted from 18 kt Everose gold, the Day-Date 128345RBR-0081 features a screw-down case back, a screw-down Twinlock winding crown, and a scratch-resistant sapphire crystal with a Cyclops lens over the date — all contributing to water resistance of 100 metres / 330 feet. The bezel is set with diamonds, adding further brilliance to the warm rose-gold case.
The silver dial is set with diamonds and features 10 baguette-cut diamonds as hour markers, while the signature day and date displays appear in apertures for immediate legibility. The watch is worn on an 18 kt Everose gold President bracelet composed of semi-circular three-piece links, secured by a concealed folding Crownclasp.
Powering the watch is Rolex Calibre 3255, a perpetual, mechanical, self-winding movement offering a precision rating of -2/+2 seconds per day after casing and approximately 70 hours of power reserve. The oscillator incorporates a paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers, and the movement carries Superlative Chronometer certification, combining COSC testing with Rolex's own post-casing standards.
