Housed in a 42mm monobloc Oyster case crafted from 18kt yellow gold, the Sky-Dweller 336938-0008 features a fluted, bidirectional rotatable Ring Command bezel — the mechanical interface through which the watch's complications are set. A screw-down case back and Twinlock winding crown contribute to water resistance rated to 100 metres, while a scratch-resistant sapphire crystal with Cyclops lens over the date ensures clarity at a glance.
The bright green dial is fitted with a Chromalight display offering long-lasting blue luminescence for low-light legibility. Month is indicated through 12 apertures arranged around the dial's circumference, while an instantaneous annual calendar appears at 3 o'clock and a 24-hour off-centre disc tracks a second time zone — all managed by the manufacture Rolex Calibre 9002, a perpetual, mechanical self-winding movement accurate to -2/+2 seconds per day after casing, with a power reserve of approximately 72 hours.
The watch rides on an 18kt yellow gold Jubilee bracelet with five-piece links, secured by a folding Oysterclasp equipped with an Easylink 5mm comfort extension link. The Calibre 9002 further benefits from a paramagnetic blue Parachrom hairspring and Paraflex shock absorbers, and winds bidirectionally via a Perpetual rotor.
