Measuring 28 mm, the Oyster case is crafted in Yellow Rolesor — a combination of Oystersteel and yellow gold — and features a monobloc middle case, screw-down case back, and a screw-down Twinlock winding crown for water resistance to 100 metres. The bezel is set with diamonds, while a scratch-resistant sapphire crystal with a Cyclops lens magnifies the date display.
The white mother-of-pearl dial is itself set with diamonds held in 18 kt gold settings, creating a play of light across the surface. Hours, minutes, and seconds hands are joined by an instantaneous date function with rapid setting, and a stop-seconds mechanism allows for precise time adjustment.
Power comes from Rolex Calibre 2236, a perpetual mechanical self-winding movement with a Syloxi silicon hairspring, Paraflex shock absorbers, bidirectional winding via a Perpetual rotor, and a power reserve of approximately 55 hours. The watch carries Superlative Chronometer certification — COSC plus Rolex certification after casing — achieving a precision of -2/+2 seconds per day. The Yellow Rolesor Jubilee bracelet closes with a concealed folding Crownclasp.
