Reference 128396TBR-0024 presents the 36 mm Day-Date in a platinum Oyster case built around a monobloc middle case, screw-down case back, and a screw-down Twinlock winding crown — delivering waterproofness to 100 metres / 330 feet. Scratch-resistant sapphire crystal with a Cyclops lens over the date sits above the vivid bright blue dial, which is set with 10 baguette-cut diamonds in place of hour markers and framed by a bezel set entirely with diamonds.
Power comes from the Calibre 3255, a perpetual mechanical self-winding movement manufactured by Rolex. It beats with a paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers, delivers a precision of -2/+2 seconds per day after casing, and carries approximately 70 hours of power reserve. The movement holds Superlative Chronometer certification, reflecting both COSC testing and Rolex's own certification after casing.
The platinum President bracelet, featuring semi-circular three-piece links, secures via a concealed folding Crownclasp. Functions include instantaneous day and date display in twin apertures with secure rapid-setting, stop-seconds for precise time adjustment, and centre hour, minute, and seconds hands.
