Reference 228396TBR-0020 presents the Day-Date 40 in a 40 mm Oyster case crafted from platinum, featuring a bezel set with diamonds. The scratch-resistant sapphire crystal incorporates a Cyclops lens over the date, while the screw-down winding crown employs Rolex's Twinlock double waterproofness system for water resistance to 100 metres. The monobloc middle case and screw-down case back complete the Oyster architecture.
The green dial is dressed with Roman numeral hour markers, lending the watch a distinguished, classical character. It is paired with a platinum President bracelet composed of semi-circular three-piece links and secured by a concealed folding Crownclasp.
Powering the watch is the Calibre 3255, a perpetual mechanical self-winding movement from Manufacture Rolex. It delivers a precision of -2/+2 seconds per day after casing, an approximately 70-hour power reserve, bidirectional winding via a Perpetual rotor, and an oscillator equipped with a paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers. The movement carries Superlative Chronometer certification, combining COSC rating with Rolex's own post-casing certification.
