Built around a 36 mm monobloc middle case in 18 kt Everose gold, reference 128345RBR-0084 features a screw-down case back, a screw-down Twinlock winding crown, and scratch-resistant sapphire crystal with a Cyclops lens over the date. The case is waterproof to 100 metres / 330 feet and the bezel is set with diamonds throughout.
The blue-green dial is itself set with diamonds and displays the time via 10 baguette-cut diamond hour markers. Day and date are shown through instantaneous apertures with secure rapid-setting, while a stop-seconds function allows for precise time adjustment. The diamond-set President bracelet in 18 kt Everose gold fastens with a concealed folding Crownclasp.
Powering the watch is the Calibre 3255, a perpetual mechanical self-winding movement from Manufacture Rolex. It delivers a precision of -2/+2 seconds per day after casing, an approximately 70-hour power reserve via bidirectional Perpetual rotor winding, and features a paramagnetic blue Parachrom hairspring with high-performance Paraflex shock absorbers. The movement carries Superlative Chronometer certification, reflecting COSC qualification followed by Rolex certification after casing.
