Housed in a 36 mm Oyster case crafted from 18kt yellow gold, this Day-Date 36 features a monobloc middle case, screw-down case back, and a screw-down Twinlock winding crown providing waterproofness to 100 metres / 330 feet. The bezel is set with diamonds, and scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case construction.
The white mother-of-pearl dial is itself set with diamonds, with hour positions marked by 10 baguette-cut diamonds. Day and date displays appear in apertures at the dial, with instantaneous change and secure rapid-setting. The diamond-set President bracelet in 18kt yellow 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, high-performance Paraflex shock absorbers, approximately 70 hours of power reserve, and a precision rating of -2/+2 seconds per day after casing. The movement carries Superlative Chronometer certification, combining COSC certification with Rolex's own certification after casing.
