Measuring 42mm across, the Oyster case is rendered in Yellow Rolesor — a combination of Oystersteel and yellow gold — and features a monobloc middle case, solid case back, and screw-down winding crown with Twinlock double waterproofness. The bidirectional rotatable fluted bezel functions as the Rolex Ring Command interface, while scratch-resistant sapphire crystal with a Cyclops lens over the date keeps the dial protected. Water resistance extends to 100 metres / 330 feet.
The champagne dial is equipped with a Chromalight display offering long-lasting blue luminescence for enhanced legibility. The month is indicated through 12 apertures arranged around the dial's circumference, while the instantaneous annual calendar and second time zone appear at 3 o'clock and on an off-centre 24-hour disc respectively, covering the full scope of the Sky-Dweller's complications.
Power comes from the Calibre 9002, a COSC-certified perpetual mechanical self-winding movement with a precision rating of -2/+2 seconds per day after casing and a power reserve of approximately 72 hours. A paramagnetic blue Parachrom hairspring and Paraflex shock absorbers contribute to the movement's resilience. The five-piece-link Jubilee bracelet in Yellow Rolesor fastens via a folding Oysterclasp fitted with an Easylink 5mm comfort extension link.
