Crafted entirely in 18 kt white gold, the 36 mm case of reference 128349RBR-0051 is built on Rolex's Oyster architecture — a monobloc middle case complemented by a screw-down case back and screw-down winding crown with Twinlock double waterproofness, delivering water resistance to 100 metres. A scratch-resistant sapphire crystal with a Cyclops lens over the date sits above the brilliant bright blue dial, which is adorned with 10 baguette-cut diamonds at the hour positions. The bezel is set with diamonds, completing an all-around diamond presence that distinguishes this particular execution of the Day-Date.
The President bracelet, rendered in 18 kt white gold with its signature semi-circular three-piece links, fastens via a concealed folding Crownclasp. Powering the watch is the Calibre 3255, a perpetual mechanical self-winding movement manufactured by Rolex that delivers a power reserve of approximately 70 hours and a precision rating of -2/+2 seconds per day after casing. Its oscillator features a paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers, contributing to the movement's Superlative Chronometer certification — a designation reflecting both COSC validation and Rolex's own post-casing standards.
Functions include centre hour, minute, and seconds hands alongside instantaneous day and date display in dedicated apertures with secure rapid-setting and stop-seconds for precise time adjustment. Production year is 2024.
