Housed in a 31 mm round Oystersteel case, this Datejust 31 is built around the Oyster architecture: a monobloc middle case, screw-down case back, and a screw-down winding crown featuring the Twinlock double waterproofness system, together delivering water resistance to 100 metres / 330 feet. Scratch-resistant sapphire crystal with a Cyclops lens over the date keeps the dial easy to read at a glance.
The pink dial is fitted with index hour markers and a Chromalight display offering long-lasting blue luminescence. The domed bezel frames the dial with a clean, unfussy profile, while the Oystersteel Jubilee bracelet — composed of five-piece links — fastens with a concealed folding Crownclasp for a secure, refined fit on the wrist.
Power comes from Calibre 2236, a perpetual, mechanical, self-winding movement from Manufacture Rolex. The calibre runs at -2/+2 seconds per day after casing, carries a Superlative Chronometer designation reflecting both COSC and Rolex certification, and offers approximately 55 hours of power reserve. Its Syloxi silicon hairspring with patented geometry and Paraflex shock absorbers contribute to its precision and resilience.
