Measuring 31 mm across, the case is built around a monobloc middle case with a screw-down case back and screw-down Twinlock winding crown, delivering water resistance to 100 metres. Scratch-resistant sapphire crystal protects the dial, with a Cyclops lens positioned over the date for easy reading, while the domed bezel is set with diamonds for a distinct finishing touch.
Inside, Rolex Calibre 2236 — a perpetual, mechanical, self-winding movement — provides a precision rating of -2/+2 seconds per day after casing, qualifying it as a Superlative Chronometer under both COSC and Rolex's own post-casing certification. A Syloxi silicon hairspring with patented geometry and Paraflex shock absorbers support the oscillator, while bidirectional winding via a Perpetual rotor yields approximately 55 hours of power reserve. Functions include centre hour, minute, and seconds hands, instantaneous date with rapid setting, and stop-seconds for precise time setting.
The Yellow Rolesor Oyster bracelet is composed of three-piece solid links and fastens with a folding Oysterclasp equipped with an Easylink 5 mm comfort extension link, allowing for easy on-wrist adjustment.
