Reference 128396TBR-0022 presents the Day-Date 36 in a full platinum expression. The 36 mm Oyster case is built around a monobloc middle case with a screw-down case back and screw-down Twinlock winding crown, offering waterproofness to 100 metres. A scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case architecture, while the bezel is set throughout with diamonds.
The white mother-of-pearl dial is itself set with diamonds, and hour markers take the form of 10 baguette-cut diamonds, lending the face a layered depth that shifts with the light. Day and date are displayed instantaneously through twin apertures, with secure rapid-setting and stop-seconds for precise time adjustment.
Power comes from the Calibre 3255, a perpetual, mechanical, self-winding movement manufactured by Rolex. It features a paramagnetic blue Parachrom hairspring, high-performance Paraflex shock absorbers, bidirectional winding via a Perpetual rotor, and a power reserve of approximately 70 hours. The movement carries Superlative Chronometer certification, reflecting COSC testing followed by Rolex certification after casing, achieving a precision of -2/+2 seconds per day. The platinum President bracelet closes with a concealed folding Crownclasp.
