Housed in an 18kt white gold Oyster case measuring 31mm, this Datejust 31 features a monobloc middle case with a screw-down case back and screw-down winding crown secured by Rolex's Twinlock double waterproofness system. Scratch-resistant sapphire crystal with a Cyclops lens over the date protects the dial, and the watch is waterproof to 100 metres / 330 feet. The bezel is set with diamonds, adding a layer of brilliance to the white gold case.
The bright black dial is appointed with Roman numeral hour markers, offering a striking contrast that draws the eye across the face. The President bracelet in 18kt white gold features semi-circular three-piece links and fastens via a concealed folding Crownclasp, completing a cohesive all-white-gold presentation on the wrist.
Powering the watch is the Calibre 2236, a perpetual mechanical self-winding movement made by Rolex. It incorporates a Syloxi silicon hairspring with patented geometry, high-performance Paraflex shock absorbers, and bidirectional winding via a Perpetual rotor. The movement delivers a precision of -2/+2 seconds per day after casing, an approximately 55-hour power reserve, and carries Superlative Chronometer certification — reflecting both COSC testing and Rolex's own post-casing standards.
