At 28 mm, the Oyster case is constructed with a monobloc middle case, screw-down case back, and a screw-down Twinlock winding crown, delivering water resistance to 100 metres. A domed bezel frames scratch-resistant sapphire crystal fitted with a Cyclops lens over the date window, keeping legibility effortless at a glance.
The white dial is marked with Roman numerals and pairs cleanly with the warm tone of the Yellow Rolesor case. The Jubilee bracelet, rendered in the same combination of Oystersteel and yellow gold across its five-piece links, fastens with a concealed folding Crownclasp for a refined, seamless look on the wrist.
Inside runs the Rolex Caliber 2236, a perpetual mechanical self-winding movement with bidirectional winding via a Perpetual rotor and a power reserve of approximately 55 hours. Its Syloxi silicon hairspring with patented geometry and Paraflex shock absorbers contribute to a precision rating of -2/+2 seconds per day after casing, earning Superlative Chronometer certification from both COSC and Rolex.
