Crafted entirely in 18kt yellow gold, the 40mm Oyster case features a monobloc middle case construction with a screw-down case back and screw-down Twinlock winding crown, delivering waterproofness to 100 metres / 330 feet. The bezel is set with diamonds, while a scratch-resistant sapphire crystal with a Cyclops lens over the date keeps the dial clearly legible at a glance.
The black diagonal motif dial is complemented by index hour markers, and the full-length President bracelet — composed of semi-circular three-piece links in 18kt yellow gold — closes with a concealed folding Crownclasp. The combination of warm gold tones and the deep black dial gives the piece a striking, high-contrast presence on the wrist.
Powering the watch is Rolex Calibre 3255, a perpetual mechanical self-winding movement boasting a approximately 70-hour power reserve and a precision rating of -2/+2 seconds per day after casing. The oscillator employs a paramagnetic blue Parachrom hairspring alongside high-performance Paraflex shock absorbers, and the movement carries Superlative Chronometer certification reflecting both COSC and Rolex's own post-casing standards.
