At 36 mm, the Oystersteel case of this Datejust follows Rolex's Oyster architecture — a monobloc middle case joined by a screw-down case back and screw-down Twinlock winding crown for waterproofness to 100 metres / 330 feet. The bezel is set with diamonds, while the scratch-resistant sapphire crystal features a Cyclops lens positioned over the date window for easy reading.
The bright blue dial is set with diamonds mounted in 18 kt gold settings, giving the piece a distinctly jewellery-forward character without sacrificing legibility. Powering the watch is the Calibre 3235 — a perpetual, mechanical, self-winding movement from Manufacture Rolex with bidirectional winding via a Perpetual rotor, a paramagnetic blue Parachrom hairspring, Paraflex shock absorbers, approximately 70 hours of power reserve, and a precision rating of -2/+2 seconds per day after casing. The movement holds Superlative Chronometer certification, combining COSC testing with Rolex's own post-casing standards.
The Oystersteel Oyster bracelet is constructed from three-piece solid links and fastens with a folding Oysterclasp fitted with an Easylink 5 mm comfort extension link, allowing straightforward on-the-fly size adjustment. Reference 116244-0022.
