Rolex Sky-Dweller 42 mm

The Rolex Sky-Dweller 42 mm, reference 336934-0007, is a GMT watch cased in steel and gold at 42 mm across and 14.1 mm thick. The fluted bezel, always rendered in gold on this model, works with the Ring Command system to set the watch's functions through the screw-down crown. A Cyclops lens sits over the date on the sapphire crystal, magnifying the annual calendar's month display, which shows in a window around the bright black dial. Inside is the self-winding calibre 9002, giving dual time zones and roughly 72 hours of power reserve. Luminous hands and indices keep the dial legible in low light. The steel bracelet closes with a folding Oysterclasp with an Easylink extension. Its Twinlock crown seals the case to a depth of 100 metres.
