Crafted in platinum, the 40 mm Oyster case of reference 228396TBR-0021 follows Rolex's monobloc construction with a screw-down case back and screw-down winding crown employing a Twinlock double waterproofness system, offering water resistance to 100 metres. The bezel is set with diamonds, while a scratch-resistant sapphire crystal fitted with a Cyclops lens magnifies the date display below.
The dial itself is paved with diamonds and sapphires, with 8 baguette-cut diamonds and 2 baguette-cut sapphires positioned at 6 and 9 o'clock as hour markers — a composition that turns the face of the watch into a field of gemstones. Day and date are displayed instantaneously through twin apertures, with secure rapid-setting and stop-seconds functionality for precise time adjustment.
Power comes from Rolex Calibre 3255, a perpetual mechanical self-winding movement with a bidirectional Perpetual rotor, a paramagnetic blue Parachrom hairspring, Paraflex shock absorbers, and an approximate 70-hour power reserve. Precision is rated at -2/+2 seconds per day after casing, meeting Rolex's Superlative Chronometer standard — encompassing both COSC certification and Rolex's own post-casing testing. The platinum President bracelet, featuring semi-circular three-piece links, closes with a concealed folding Crownclasp.
