Housed in a 42mm monobloc Oyster case crafted from 18kt yellow gold, the Sky-Dweller 336938-0005 features a fluted, bidirectional rotatable Rolex Ring Command bezel alongside a screw-down case back and a screw-down Twinlock winding crown. A scratch-resistant sapphire crystal with a Cyclops lens over the date protects the bright black dial, while water resistance extends to 100 metres / 330 feet.
The dial's Chromalight display offers a long-lasting blue luminescence for high legibility. Month indication is delivered through 12 apertures around the dial's circumference, with an instantaneous annual calendar at 3 o'clock, a 24-hour off-centre disc for a second time zone, and stop-seconds for precise time setting — all driven by the self-winding Calibre 9002, manufacture Rolex, rated to -2/+2 seconds per day after casing and offering approximately 72 hours of power reserve. The movement is COSC certified and features a paramagnetic blue Parachrom hairspring with Paraflex shock absorbers.
The watch rides on an 18kt yellow gold Jubilee bracelet with five-piece links, secured by a folding Oysterclasp fitted with an Easylink 5mm comfort extension link. This piece is offered as a complete set, including the Rolex box and Rolex card.
