Crafted from 18 kt yellow gold, the 36 mm Oyster case of reference 128398TBR-0028 features a monobloc middle case, 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 sits above the captivating green ombré dial, which is dressed with Roman numeral hour markers. The bezel is set with diamonds, lending additional brilliance to the already luminous yellow gold construction.
Powering the watch is the Manufacture Rolex Calibre 3255, a perpetual mechanical self-winding movement with a precision rating of -2/+2 seconds per day after casing and a power reserve of approximately 70 hours. The oscillator incorporates a paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers, while bidirectional winding is achieved via the Perpetual rotor. The movement carries Superlative Chronometer certification, reflecting both COSC standards and Rolex's own post-casing verification.
The President bracelet in 18 kt yellow gold, distinguished by its semi-circular three-piece links, secures with a concealed folding Crownclasp for a seamless silhouette on the wrist. Functions include instantaneous day and date displays in dedicated apertures, a stop-seconds mechanism for precise time setting, and secure rapid-setting for both day and date complications.
