Rolex Sky-Dweller 42 mm

Rolex Sky-Dweller 42 mm, reference 336938-0004, is a GMT watch cased in 18 ct yellow gold with a 42 mm diameter and 14.1 mm thickness. The fluted bezel forms part of the Ring Command system, working with the screw-down crown to set the watch's functions. A Cyclops lens sits over the date on the sapphire crystal, above a champagne-colour dial with luminous hands and indices. Inside is the calibre 9002, a self-winding perpetual movement with a power reserve of about 72 hours. Beyond the second time zone, the watch carries an annual calendar that needs correction only once a year, in March. It is fitted to a yellow gold Jubilee bracelet with a folding Oysterclasp and Easylink extension. The screw-down crown holds the case to its 100 metre rating.
