Presented in an 18kt yellow gold Oyster case measuring 40mm, this Day-Date 40 features a monobloc middle case with a screw-down case back and screw-down Twinlock winding crown, offering water resistance to 100 metres. The bezel is set with diamonds, while scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case.
The silver dial is dressed with bevelled Roman numerals and displays the full day and date through instantaneous apertures with secure rapid-setting. An 18kt yellow gold President bracelet — defined by its semi-circular three-piece links — secures via a concealed folding Crownclasp.
Power comes from 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. The oscillator uses a paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers, and the movement carries Superlative Chronometer certification with a precision rating of -2/+2 seconds per day after casing.
