Rolex Sky-Dweller 42 mm

The Rolex Sky-Dweller 336933-0003 is a GMT watch measuring 42 mm across in steel and gold. The case stands 14.1 mm thick and pairs with a fluted bezel in gold, part of the Ring Command system that lets the wearer set the watch's functions through the bezel itself. A sapphire crystal with a Cyclops lens sits over the date, and the bright black dial shows luminous hands and indices. Inside is the self-winding calibre 9002, a chronometer-certified movement offering dual time zones and an annual calendar that only needs adjusting in March. The screw-down crown works with the same steel and gold construction as the Oyster bracelet, which closes on a folding Oysterclasp with the Easylink comfort extension. Rolex rates the case to 100 metres.
