Housed in a 40mm 18kt yellow gold Oyster case, this Day-Date 40 features a monobloc middle case construction with a screw-down case back and a screw-down Twinlock winding crown, offering water resistance to 100 metres. Scratch-resistant sapphire crystal with a Cyclops lens over the date keeps the display clear, while the bezel is set with diamonds for a distinctly formal character.
The champagne dial is dressed with Roman numeral hour markers and presents the day and date through instantaneous apertures with secure rapid-setting. Underneath, the Calibre 3255 perpetual mechanical self-winding movement operates with a precision of -2/+2 seconds per day after casing, a power reserve of approximately 70 hours, and a paramagnetic blue Parachrom hairspring paired with Paraflex shock absorbers. It carries Superlative Chronometer certification, reflecting both COSC testing and Rolex's own post-casing standards.
The watch rides on an 18kt yellow gold President bracelet with semi-circular three-piece links and a concealed folding Crownclasp, completing the reference's characteristic head-of-state presence on the wrist.
