Housed in a 36 mm Oyster case crafted from 18 kt Everose gold, reference 128235-0078 features a monobloc middle case, screw-down case back, and a screw-down Twinlock winding crown that together deliver waterproofness to 100 metres. A scratch-resistant sapphire crystal with a Cyclops lens over the date aperture completes the case. The fluted bezel adds further texture to the warm rose-gold tone throughout.
The white mother-of-pearl dial is set with 10 baguette-cut diamonds at the hour positions, providing a refined interplay of natural iridescence and brilliant stone. Day and date displays appear in separate apertures with instantaneous, secure rapid-setting, and a stop-seconds function allows for precise time adjustment.
Power comes from Rolex Calibre 3255, a perpetual mechanical self-winding movement with bidirectional winding via a Perpetual rotor, a paramagnetic blue Parachrom hairspring, Paraflex shock absorbers, approximately 70 hours of power reserve, and a precision rating of -2/+2 seconds per day after casing. The movement holds Superlative Chronometer certification, reflecting both COSC standards and Rolex's own post-casing verification. The watch rides on an 18 kt Everose gold President bracelet with semi-circular three-piece links and a concealed folding Crownclasp.
