Rolex Sky-Dweller 42 mm

The Rolex Sky-Dweller 42 mm, reference 336934-0005, is a GMT watch in steel and gold with a 42 mm case. The case measures 14.1 mm thick and carries a fluted bezel, always shown in gold on this model. A sapphire crystal with a Cyclops lens sits over the date, and the bright blue dial has luminous hands and indices. Inside is the self-winding calibre 9002, a chronometer-certified movement with dual time zones and an annual calendar that only needs adjusting in March. The screw-down crown works with the Ring Command bezel to set these functions. The steel Oyster bracelet closes with a folding Oysterclasp fitted with an Easylink extension link for extra comfort. Rolex rates the case to 100 metres.
