Rolex Sky-Dweller 42 mm

Rolex's Sky-Dweller 42 mm, reference 336938-0001, is a GMT watch cased in 18 ct yellow gold. The case measures 42 mm across and 14.1 mm thick, with a fluted bezel that also operates the Ring Command system for setting the watch's functions. A sapphire crystal with a Cyclops lens sits over the date, and the champagne dial carries luminous hands and indices. Inside is the self-winding calibre 9002, a chronometer-certified movement combining an annual calendar with a second time zone display and 72 hours of power reserve. The month appears through apertures around the dial rather than in a single window. A solid-link Oyster bracelet in yellow gold closes with a folding Oysterclasp fitted with the Easylink comfort extension. Rolex rates the case to 100 metres.
