Measuring 34 mm in diameter, the Oystersteel case is built around a monobloc middle case with a screw-down case back and a screw-down Twinlock winding crown, delivering water resistance to 100 metres / 330 feet. A domed bezel and scratch-resistant sapphire crystal complete the case, keeping the profile clean and the dial well protected.
That dial is finished in lavender and features a Chromalight display with long-lasting blue luminescence for legibility in low light. The Oystersteel Oyster bracelet is composed of three-piece solid links and fastens with a folding Oysterclasp fitted with an Easylink 5 mm comfort extension link for a precise and comfortable fit.
Powering the watch is the perpetual, mechanical, self-winding Calibre 2232, which incorporates a Syloxi silicon hairspring with patented geometry and Paraflex shock absorbers. Bidirectional winding via the Perpetual rotor provides a power reserve of approximately 55 hours, and the movement carries Superlative Chronometer certification — reflecting both COSC testing and Rolex's own certification after casing.
