Housed in a round 18 kt yellow gold Oyster case measuring 31 mm, this Datejust 31 features a monobloc middle case, solid screw-down case back, and a screw-down winding crown secured by a Twinlock double waterproofness system. Scratch-resistant sapphire crystal with a Cyclops lens over the date protects the champagne-colour dial, and the watch is waterproof to 100 metres / 330 feet.
The 18 kt yellow gold President bracelet, distinguished by its semi-circular three-piece links, fastens with a concealed folding Crownclasp. The fluted bezel completes a look that is consistently associated with the President bracelet configuration.
Powering the watch is Rolex Calibre 2236, a perpetual, mechanical, self-winding movement with a precision rating of -2/+2 seconds per day after casing and a power reserve of approximately 55 hours. The calibre features a Syloxi silicon hairspring with patented geometry, high-performance Paraflex shock absorbers, bidirectional winding via a Perpetual rotor, and an instantaneous date display with rapid setting — and carries COSC certification.
