At 31 mm, this Datejust 31 wears the Yellow Rolesor construction across both the case and Jubilee bracelet, pairing Oystersteel with yellow gold throughout. The domed bezel is set with diamonds, while scratch-resistant sapphire crystal with a Cyclops lens over the date keeps the dial legible at a glance. A monobloc middle case, screw-down case back, and screw-down Twinlock winding crown work together to deliver water resistance to 100 metres / 330 feet.
The silver dial is itself set with diamonds, and the large VI marker is distinguished by a cluster of 11 diamonds — a detail that brings depth to the Roman numeral layout. Inside, Rolex Calibre 2236 drives the watch with a perpetual, mechanical, self-winding movement offering a power reserve of approximately 55 hours. The oscillator features a Syloxi silicon hairspring with patented geometry and high-performance Paraflex shock absorbers, achieving a precision of -2/+2 seconds per day after casing.
Calibre 2236 holds Superlative Chronometer certification, reflecting both COSC testing and Rolex's own certification after casing. Functions include centre hour, minute, and seconds hands, instantaneous date with rapid setting, and stop-seconds for precise time adjustment. The Jubilee bracelet closes with a concealed folding Crownclasp for a seamless, refined finish.
