Housed in a 36 mm round Oyster case constructed from Everose Rolesor — Rolex's combination of Oystersteel and Everose gold — the Datejust 126201-0031 features a monobloc middle case, solid case back, and a screw-down winding crown with Twinlock double waterproofness. The domed bezel sits above a scratch-resistant sapphire crystal fitted with a Cyclops lens over the date window, and the watch is waterproof to 100 metres / 330 feet.
The silver palm motif dial draws the eye with its distinctive decorative pattern, while Chromalight display hands and indices provide a long-lasting blue luminescence for legibility in low light. The date complication offers instantaneous setting with rapid adjustment, and the stop-seconds function allows for precise time synchronization.
Power comes from the self-winding Calibre 3235, a perpetual mechanical movement rated to -2/+2 seconds per day after casing and COSC certified, with a power reserve of approximately 70 hours. The movement features a paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers. The Jubilee bracelet, built in five-piece links of matching Everose Rolesor, fastens with a folding Oysterclasp equipped with an Easylink 5 mm comfort extension link.
