Rolex Sky-Dweller 42 mm

The Rolex Sky-Dweller 336239-0002 is a GMT watch in 18 ct white gold measuring 42 mm across. The case stands 14.1 mm thick and pairs with a fluted white gold bezel operated through the Ring Command system at the crown. A sapphire crystal with a Cyclops lens sits over the date, and the bright black dial carries luminous hands and indices. Inside is the self-winding calibre 9002, a chronometer-certified movement combining a GMT function with an annual calendar and offering around 72 hours of power reserve. The screw-down crown works with a Twinlock system to seal the case. A black Oysterflex bracelet closes on a white gold folding Oysterclasp with Glidelock extension. It stays water resistant to a depth of 100 metres.
