Reference 228396TBR-0027 presents the Day-Date 40 in its most opulent form: a 40 mm Oyster case crafted in platinum, housing a meteorite dial adorned with 10 baguette-cut diamonds at the hour markers. The bezel is set with diamonds, and the scratch-resistant sapphire crystal features a Cyclops lens magnifying the date display. The monobloc middle case pairs with a screw-down case back and a screw-down Twinlock winding crown, providing water resistance to 100 metres / 330 feet.
On the wrist, the watch rides on a platinum President bracelet with semi-circular three-piece links, secured by a concealed folding Crownclasp. Inside beats the Calibre 3255, a perpetual mechanical self-winding movement from Manufacture Rolex delivering a precision of -2/+2 seconds per day after casing — meeting Superlative Chronometer standards through COSC certification and Rolex's own post-casing verification. The movement offers approximately 70 hours of power reserve, bidirectional winding via a Perpetual rotor, and features a paramagnetic blue Parachrom hairspring alongside high-performance Paraflex shock absorbers.
This example is presented as a complete set, accompanied by its original box and papers. Day and date are displayed instantaneously in dedicated apertures, with a stop-seconds function enabling precise time setting.
