Housed in a 31mm monobloc middle case crafted from 18kt white gold, this Datejust 31 features a screw-down case back, a screw-down Twinlock winding crown, and scratch-resistant sapphire crystal with a Cyclops lens over the date window. The bezel is set with diamonds, and the watch carries a water resistance rating of 100 metres / 330 feet.
The white dial is dressed with Roman numeral hour markers and is complemented by an 18kt white gold President bracelet composed of semi-circular three-piece links, secured by a concealed folding Crownclasp. Together, the case and bracelet form a cohesive all-white-gold presentation.
Power comes from the Calibre 2236, a perpetual mechanical self-winding movement manufactured by Rolex, offering bidirectional winding via a Perpetual rotor, a power reserve of approximately 55 hours, and a precision rating of -2/+2 seconds per day after casing. The oscillator employs a Syloxi silicon hairspring with patented geometry alongside high-performance Paraflex shock absorbers, and the movement holds Superlative Chronometer certification reflecting both COSC and Rolex post-casing standards.
