Crafted from platinum, the 40 mm Oyster case of this Day-Date 40 is built around a monobloc middle case with a screw-down case back and a screw-down Twinlock winding crown, offering water resistance to 100 metres. The bezel is set with diamonds, while a scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case architecture.
The white dial is laid out with Roman numeral hour markers and displays the day and date through instantaneous apertures with secure rapid-setting. The President bracelet, constructed from platinum with semi-circular three-piece links, fastens via a concealed folding Crownclasp for a seamless look on the wrist.
Power comes from the Calibre 3255, a perpetual mechanical self-winding movement manufactured by Rolex. It beats with a paramagnetic blue Parachrom hairspring, employs Paraflex shock absorbers, winds bidirectionally via a Perpetual rotor, and delivers approximately 70 hours of power reserve. The movement carries Superlative Chronometer certification, combining COSC testing with Rolex's own post-casing standards. This example is dated 2023.
