At 31 mm, this Datejust 31 features a round case constructed in White Rolesor — a combination of Oystersteel and white gold — with a monobloc middle case, solid case back, and a screw-down winding crown utilizing the Twinlock double waterproofness system. The bezel is set with diamonds, while a scratch-resistant sapphire crystal with a Cyclops lens over the date window completes the case. Water resistance is rated to 100 metres / 330 feet.
The pink dial is equipped with a Chromalight display offering long-lasting blue luminescence for high legibility. Date functionality is delivered via an instantaneous date display with rapid setting, alongside centre hour, minute, and seconds hands and a stop-seconds mechanism for precise time setting.
Powering the watch is the Calibre 2236, a perpetual, mechanical, self-winding movement from Manufacture Rolex, offering a precision of -2/+2 seconds per day after casing and approximately 55 hours of power reserve. The oscillator features a Syloxi hairspring in silicon with patented geometry and high-performance Paraflex shock absorbers, with bidirectional self-winding via a Perpetual rotor. The Oystersteel Jubilee bracelet closes with a concealed folding Crownclasp.
