Built around a 36 mm round Oyster case in Everose Rolesor — Rolex's combination of Oystersteel and Everose gold — the Datejust 126201-0037 features a monobloc middle case, solid case back, and a screw-down winding crown equipped with the Twinlock double waterproofness system. A domed bezel frames the scratch-resistant sapphire crystal, which carries a Cyclops lens positioned over the date window. The case is waterproof to 100 metres / 330 feet.
The silver dial presents a palm motif set with diamonds in 18 kt gold settings, bringing an ornate, nature-inspired character to the 36 mm format. Matching the case materials, the Jubilee bracelet is composed of five-piece links in Everose Rolesor and fastens via a folding Oysterclasp with an Easylink 5 mm comfort extension link.
Power comes from the Calibre 3235, a perpetual, mechanical, self-winding movement manufactured by Rolex and COSC certified to a precision of -2/+2 seconds per day after casing. A paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers contribute to its resilience, while bidirectional winding via the Perpetual rotor delivers approximately 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.
