Housed in a 36 mm round Oyster case constructed from Everose Rolesor — a blend of Oystersteel and Everose gold — the Datejust 126201-0015 features a monobloc middle case, solid case back, and a screw-down winding crown with Twinlock double waterproofness. The domed bezel frames a scratch-resistant sapphire crystal equipped with a Cyclops lens over the date window, while the case maintains waterproofness to 100 metres / 330 feet.
The white dial is accompanied by a date complication with rapid setting, center hour, minute, and seconds hands, and stop-seconds functionality for precise time setting. The Jubilee bracelet, composed of five-piece links in matching Everose Rolesor, fastens via a folding Oysterclasp fitted with an Easylink 5 mm comfort extension link.
Inside runs the perpetual, mechanical, self-winding Calibre 3235, a Manufacture Rolex movement beating with a paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers. Bidirectional winding via the Perpetual rotor provides a power reserve of approximately 70 hours, and the calibre is COSC certified.
