Crafted in Yellow Rolesor — Rolex's combination of Oystersteel and yellow gold — the 31 mm Oyster case features a monobloc middle case, screw-down case back, and a screw-down Twinlock winding crown for waterproofness to 100 metres. A fluted bezel frames scratch-resistant sapphire crystal fitted with a Cyclops lens over the date window.
The silver dial is set with diamonds held in 18 kt gold settings, while the three-piece solid-link Oyster bracelet in Yellow Rolesor fastens with a folding Oysterclasp equipped with an Easylink 5 mm comfort extension link. At the heart of the watch is Calibre 2236, a perpetual mechanical self-winding movement carrying Superlative Chronometer certification — reflecting both COSC standards and Rolex's own post-casing verification — with a precision rating of -2/+2 seconds per day.
Calibre 2236 runs on bidirectional self-winding via a Perpetual rotor and delivers approximately 55 hours of power reserve. Its oscillator features a Syloxi hairspring in silicon with patented geometry and high-performance Paraflex shock absorbers, while a stop-seconds mechanism allows for precise time setting alongside instantaneous date with rapid setting.
