Crafted in platinum, the 40 mm Oyster case of this Day-Date features a monobloc middle case construction with a screw-down case back and a screw-down Twinlock winding crown offering double waterproofness. The bezel is set with diamonds, while a scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case. Water resistance is rated to 100 metres / 330 feet.
The bright blue dial is appointed with Roman numeral hour markers, giving the piece a classical character. Instantaneous day and date displays appear in dedicated apertures with secure rapid-setting, and a stop-seconds function allows for precise time setting. The platinum President bracelet, featuring semi-circular three-piece links, closes with a concealed folding Crownclasp.
Power comes from the Calibre 3255, a perpetual mechanical self-winding movement from Manufacture Rolex. The oscillator uses a paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers, delivering a precision rating of -2/+2 seconds per day after casing. The movement is certified as a Superlative Chronometer, meeting both COSC standards and Rolex's own certification after casing, with a power reserve of approximately 70 hours sustained through bidirectional winding via the Perpetual rotor.
