Reference 128349RBR-0052 is a 2024 Rolex Day-Date measuring 36 mm across, housed in an 18 kt white gold Oyster case built around a monobloc middle case with a screw-down case back and screw-down Twinlock winding crown. The bezel is fully set with diamonds, and a scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case. Water resistance is rated to 100 metres / 330 feet.
The bright blue dial is set with 10 baguette-cut diamonds serving as hour markers, giving the face a bold yet refined character. Beneath it runs the Calibre 3255, a perpetual mechanical self-winding movement produced by Rolex, delivering a precision of -2/+2 seconds per day after casing and a power reserve of approximately 70 hours. The movement features a paramagnetic blue Parachrom hairspring, high-performance Paraflex shock absorbers, and bidirectional winding via a Perpetual rotor. It carries Superlative Chronometer certification, reflecting both COSC and Rolex's own post-casing standards.
The watch is worn on an 18 kt white gold diamond-set President bracelet secured by a concealed folding Crownclasp, maintaining the clean, uninterrupted lines of the case and dial. Functions include center hour, minute, and seconds hands alongside instantaneous day and date display in apertures with secure rapid-setting and stop-seconds for precise time adjustment.
