Reference 126231-0037 presents the Datejust 36 in a round 36 mm case crafted from Oystersteel and Everose gold. The case follows Rolex's Oyster architecture with a monobloc middle case, solid case back, and a screw-down winding crown secured by the Twinlock double waterproofness system, delivering water resistance to 100 metres / 330 feet. A scratch-resistant sapphire crystal sits above the dial, complete with a Cyclops lens magnifying the date.
The silver dial carries a palm motif adorned with diamonds set in 18 kt gold settings, giving each glance at the time a quietly ornate quality. It is paired with a five-piece link Jubilee bracelet in Everose Rolesor, fastened by a folding Oysterclasp with an Easylink 5 mm comfort extension link.
Inside runs Rolex Calibre 3235, a perpetual mechanical self-winding movement rated to -2/+2 seconds per day after casing and bearing both COSC certification and Rolex's own Superlative Chronometer certification. The oscillator employs a paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers, with bidirectional winding via a Perpetual rotor. Functions include centre hour, minute, and seconds hands, an instantaneous date with rapid setting, and stop-seconds for precise time setting.
