Reference 228345RBR-0026 presents the Day-Date 40 in an 18 kt Everose gold Oyster case measuring 40 mm across. The bezel is set with diamonds, while a screw-down winding crown employing Rolex's Twinlock double waterproofness system and a scratch-resistant sapphire crystal with Cyclops lens over the date complete the case. Water resistance extends to 100 metres / 330 feet.
The mother-of-pearl dial is itself set with diamonds and features 10 baguette-cut diamond hour markers, lending the piece a layered brilliance that draws on both the iridescent dial material and the precision-cut stones. The President bracelet, rendered in 18 kt Everose gold with semi-circular three-piece links, fastens via a concealed folding Crownclasp.
Inside beats Rolex Calibre 3255, a perpetual mechanical self-winding movement with a power reserve of approximately 70 hours and a precision rating of -2/+2 seconds per day after casing. The oscillator features a paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers, and the movement carries Superlative Chronometer certification — reflecting both COSC and Rolex's own post-casing standards. Production year: 2024.
