Crafted in 18 kt Everose gold, the 36 mm Oyster case of reference 128395TBR-0020 features a monobloc middle case, screw-down case back, and a screw-down winding crown with Rolex's Twinlock double waterproofness system, delivering water resistance to 100 metres. A scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case, while the diamond-set bezel adds a further layer of brilliance.
The green aventurine dial is itself set with diamonds, and the hour markers in 18 kt gold carry 32 diamonds, with the Roman VI and IX numerals in 18 kt gold set with an additional 24 diamonds. The President bracelet, rendered in 18 kt Everose gold with semi-circular three-piece links, secures via a concealed folding Crownclasp for a seamless profile on the wrist.
Powering the watch is the Calibre 3255, a perpetual mechanical self-winding movement certified as a Superlative Chronometer to a precision of -2/+2 seconds per day after casing. The movement features a paramagnetic blue Parachrom hairspring, high-performance Paraflex shock absorbers, bidirectional winding via a Perpetual rotor, and an approximately 70-hour power reserve, with instantaneous day and date display via secure rapid-setting apertures.
