Housed in a 36 mm 18 kt Everose gold Oyster case, this Day-Date features a monobloc middle case with a screw-down case back and screw-down Twinlock winding crown, offering water resistance to 100 metres / 330 feet. The bezel is set with diamonds, and a scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case.
The slate dial is itself set with diamonds in 18 kt gold settings, with baguette-cut diamonds positioned at 6 and 9 o'clock. The day and date each appear instantaneously in dedicated apertures, while the centre hour, minute, and seconds hands provide clear timekeeping. The diamond-set President bracelet in 18 kt Everose gold fastens with a concealed folding Crownclasp.
Power comes from the Rolex Calibre 3255, a perpetual mechanical self-winding movement with bidirectional winding via a Perpetual rotor, a paramagnetic blue Parachrom hairspring, Paraflex shock absorbers, a power reserve of approximately 70 hours, and a precision rating of -2/+2 seconds per day after casing. The movement carries Superlative Chronometer certification, reflecting both COSC and Rolex's own post-casing standards.
