The 36mm Oystersteel case of reference 116244-0037 is built around a monobloc middle case with a screw-down case back and screw-down winding crown featuring the Twinlock double waterproofness system, delivering water resistance to 100 metres. A scratch-resistant sapphire crystal sits above the dial, complete with a Cyclops lens magnifying the date display, while the bezel is set throughout with diamonds.
At the heart of the watch is the bronze dial rendered in a wave pattern and set with diamonds across its surface, with Arabic numerals that are themselves diamond-set — a combination that gives the piece a distinctly ornate character. The Oyster bracelet in Oystersteel uses three-piece solid links and fastens via a folding Oysterclasp with an Easylink 5 mm comfort extension link.
Power comes from Rolex Calibre 3235, a perpetual mechanical self-winding movement with bidirectional winding via a Perpetual rotor and an approximate 70-hour power reserve. The oscillator features a paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers, achieving a precision of -2/+2 seconds per day after casing. The movement carries Superlative Chronometer certification, reflecting both COSC and Rolex's own post-casing standards.
