Reference 128349RBR-0050 presents the Day-Date 36 in an 18 kt white gold Oyster case measuring 36 mm across. The monobloc middle case is completed by a screw-down case back and a screw-down Twinlock winding crown, delivering waterproofness to 100 metres. A scratch-resistant sapphire crystal with a Cyclops lens over the date sits above a diamond-set bezel, while the overall architecture reflects the Day-Date's position at the top of the Rolex range.
The white mother-of-pearl dial is itself set with diamonds and features 10 baguette-cut diamonds as hour markers. The diamond-set President bracelet in 18 kt white gold is secured by a concealed folding Crownclasp, creating an uninterrupted line around the wrist. Together, the dial and bracelet bring a consistent theme of diamond setting to every element of the watch.
Inside runs the Rolex Calibre 3255, a perpetual, mechanical, self-winding movement certified as a Superlative Chronometer to a precision of -2/+2 seconds per day after casing. A paramagnetic blue Parachrom hairspring and Paraflex shock absorbers underpin its reliability, bidirectional winding via the Perpetual rotor provides a power reserve of approximately 70 hours, and instantaneous day and date displays with secure rapid-setting round out the functionality of this 2024 production piece.
