Reference 128348RBR-0078 brings together an 18 kt yellow gold Oyster case measuring 36 mm with a bezel set with diamonds. The architecture follows Rolex's monobloc middle case construction, finished with a screw-down case back and a screw-down Twinlock winding crown for waterproofness to 100 metres. A scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case.
At the heart of the dial, a bright green surface is set with 10 baguette-cut diamonds serving as hour markers, lending the watch an intensely vibrant character. The President bracelet in 18 kt yellow gold, featuring semi-circular three-piece links, secures via a concealed folding Crownclasp for a clean, uninterrupted profile on the wrist.
Power comes from the Calibre 3255, a perpetual mechanical self-winding movement manufactured by Rolex. It offers a power reserve of approximately 70 hours, a precision rating of -2/+2 seconds per day after casing, and features a paramagnetic blue Parachrom hairspring alongside Paraflex shock absorbers. The movement displays the hour, minute, seconds, and offers instantaneous day and date indications with stop-seconds for precise time setting, certified as a Superlative Chronometer to both COSC and Rolex standards.
