Housed in a 36 mm Oyster case crafted from 18 kt Everose gold, the Day-Date 36 ref. 128235-0079 features a fluted bezel and a screw-down winding crown with Twinlock double waterproofness, offering water resistance to 100 metres. The scratch-resistant sapphire crystal incorporates a Cyclops lens over the date window, while the monobloc middle case and screw-down case back form the foundation of this Oyster architecture.
The mother of pearl dial is adorned with 10 baguette-cut diamonds at the hour positions, catching light with every glance. It displays the day and date instantaneously in dedicated apertures, complemented by centre hour, minute, and seconds hands. The concealed folding Crownclasp secures the 18 kt Everose gold diamond-set President bracelet for a seamless, elegant finish on the wrist.
Powering the watch is 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 of -2/+2 seconds per day after casing, a standard recognized under Rolex's Superlative Chronometer certification.
