Housed in a 40 mm 18 kt yellow gold Oyster case, the 228348RBR-0040 features a monobloc middle case, screw-down case back, and a screw-down Twinlock winding crown for waterproofness to 100 metres. The bezel is set with diamonds, while a scratch-resistant sapphire crystal with a Cyclops lens magnifies the date window above.
The green dial is rendered with Roman numerals and displays the instantaneous day and date through twin apertures — hallmarks of the Day-Date lineage. The 18 kt yellow gold President bracelet, composed of semi-circular three-piece links, fastens with a concealed folding Crownclasp for a seamless profile on the wrist.
Power comes from Rolex Calibre 3255, a perpetual, mechanical, self-winding movement with bidirectional winding via a Perpetual rotor and a power reserve of approximately 70 hours. Its paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers contribute to a precision rating of -2/+2 seconds per day after casing, with Superlative Chronometer certification reflecting both COSC and Rolex's own post-casing standards. This example is offered as an unworn complete set with original Rolex box and Rolex papers from 2024.
