Rolex Sky-Dweller 42 mm

The Rolex Sky-Dweller 42 mm, reference 336238-0001, is a GMT watch cased in 18 ct yellow gold at 42 mm across and 14.1 mm thick. A fluted gold bezel works with the Ring Command system to set its functions, and a sapphire crystal with a Cyclops lens sits over the date. The self-winding calibre 9002 drives the watch, giving dual time zones and an annual calendar alongside a running seconds display, and Rolex certifies it as a chronometer. The champagne dial carries luminous hands and indices, with the month shown through twelve apertures around its edge. An Oysterflex bracelet in rubber closes with a yellow gold folding Oysterclasp and Glidelock extension. The screw-down crown backs up its 100 metre water resistance rating.
