Housed in a round 36 mm case crafted from Yellow Rolesor — Rolex's combination of Oystersteel and yellow gold — the Datejust 126283RBR-0026 features a monobloc middle case, solid case back, and a screw-down winding crown with Twinlock double waterproofness, delivering water resistance to 100 metres / 330 feet. The bezel is set with diamonds, adding a layer of brilliance to the characteristic Oyster architecture.
The golden fluted motif dial offers a distinctly textured look, complemented by a Chromalight display with long-lasting blue luminescence for reliable legibility. A scratch-resistant sapphire crystal with a Cyclops lens over the date window completes the dial presentation. The Oyster bracelet, constructed from three-piece solid links in Yellow Rolesor, fastens with a folding Oysterclasp featuring an Easylink 5 mm comfort extension link.
Inside beats the perpetual, mechanical, self-winding Calibre 3235, a Manufacture Rolex movement rated to -2/+2 seconds per day after casing and COSC certified. The oscillator incorporates a paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers, while bidirectional winding via the Perpetual rotor sustains roughly 70 hours of power reserve. Functions include centre hour, minute, and seconds hands, an instantaneous date with rapid setting, and stop-seconds for precise time adjustment.
