At 31 mm, this Datejust 31 wears the iconic round Oyster case constructed from Everose Rolesor, blending Oystersteel with Everose gold. The monobloc middle case is sealed by a solid screw-down case back and a screw-down Twinlock winding crown, delivering water resistance to 100 metres / 330 feet. A scratch-resistant sapphire crystal sits above the dial, fitted with a Cyclops lens that magnifies the instantaneous date display.
The rosé-colour dial features Roman numeral hour markers and is housed beneath a domed bezel. The three-piece solid-link Oyster bracelet, also in Everose Rolesor, fastens with a folding Oysterclasp equipped with an Easylink 5 mm comfort extension link. Together, the case and bracelet form a cohesive two-toned composition.
Powering the watch is Rolex Calibre 2236, a perpetual mechanical self-winding movement with a precision rating of -2/+2 seconds per day after casing and a power reserve of approximately 55 hours. The oscillator features a Syloxi silicon hairspring with patented geometry alongside Paraflex shock absorbers, and the movement winds bidirectionally via a Perpetual rotor. The calibre is COSC certified and delivers centre hour, minute, and seconds hands, rapid date setting, and stop-seconds for precise time adjustment.
