Measuring 31mm across its round Oyster case, this Datejust 31 is constructed entirely in 18 kt yellow gold. The case features a monobloc middle, solid screw-down case back, and a screw-down winding crown with Twinlock double waterproofness, offering water resistance to 100 metres / 330 feet. A scratch-resistant sapphire crystal with a Cyclops lens magnifies the date display.
The silver dial is set with diamonds in 18 kt gold settings, while the fluted bezel adds additional texture and character to the overall composition. The watch is worn on a President bracelet — featuring semi-circular three-piece links in 18 kt yellow gold — secured by a concealed folding Crownclasp.
Powering the watch is the Calibre 2236, a perpetual, mechanical, self-winding movement manufactured by Rolex. It offers bidirectional winding via a Perpetual rotor, a precision of -2/+2 seconds per day after casing, and a power reserve of approximately 55 hours. The oscillator incorporates a Syloxi silicon hairspring with patented geometry alongside Paraflex shock absorbers, and the movement is COSC certified.
