Rolex Sky-Dweller 42 mm

The Rolex Sky-Dweller 336934-0002, a GMT watch in steel and gold, measures 42 mm across and 14.1 mm thick. The case carries a fluted gold bezel paired with the Ring Command system, and a screw-down crown backs the water resistance. A sapphire crystal with a Cyclops lens sits over the date, and the mint green dial shows luminous hands and indices for legibility. Inside is the self-winding calibre 9002, a chronometer-certified movement with 72 hours of power reserve. Beyond the GMT function, the Sky-Dweller adds an annual calendar that tracks months through a red window and needs adjustment only once a year, on 1 March. It comes on a steel Jubilee bracelet with a folding Oysterclasp and an Easylink extension for quick adjustment. Rolex rates the case to 100 metres.
