Reference 228396TBR-0043 houses a 40 mm Oyster case crafted entirely in platinum, featuring a monobloc middle case, screw-down case back, and a screw-down winding crown with Twinlock double waterproofness — rated waterproof to 100 metres. A scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case, while the bezel is lavishly set with diamonds.
The white mother-of-pearl dial is itself set with diamonds, with hour markers rendered in 10 baguette-cut diamonds that lend the face a luminous, structured elegance. Beneath, the Calibre 3255 self-winding mechanical movement — Manufacture Rolex — delivers a precision rating of -2/+2 seconds per day after casing, a Superlative Chronometer designation reflecting both COSC and Rolex's own post-casing certification. A paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers support the oscillator, while bidirectional winding via the Perpetual rotor provides approximately 70 hours of power reserve.
The platinum President bracelet, built from semi-circular three-piece links, secures via a concealed folding Crownclasp and serves as the natural complement to this Day-Date's instantaneous day and date display — a combination that has long defined the model's place at the top of the Rolex collection.
