Reference 228396TBR-0011 presents the Day-Date 40 in a 40 mm Oyster case crafted from platinum, its bezel set with diamonds and its silver dial adorned with 10 baguette-cut diamond hour markers. Scratch-resistant sapphire crystal with a Cyclops lens over the date and a screw-down Twinlock winding crown contribute to water resistance to 100 metres.
The platinum President bracelet, distinguished by its semi-circular three-piece links, secures with a concealed folding Crownclasp. The monobloc middle case and screw-down case back complete the Oyster architecture that defines this reference.
Powering the watch is the Calibre 3255 perpetual mechanical self-winding movement, offering a precision of -2/+2 seconds per day after casing, a power reserve of approximately 70 hours, and a paramagnetic blue Parachrom hairspring paired with Paraflex shock absorbers. The movement carries Superlative Chronometer certification, combining COSC standards with Rolex's own post-casing verification.
