Rolex created the Sky Dweller “for those who travel the world.” The chronometer-certified model debuted at Basalworld 2012, with features including the all-new caliber 9001, dual time zone display, annual calendar and a 72-hour power reserve. A 42mm timepiece, the Sky Dweller is available in white gold (Ref. 326939), everose gold (Ref. 326935), and yellow gold (Ref. 326938). Yellow and white gold models come with Oyster-style bracelets, while the everose option features a crocodile strap. A truly unique timepiece, the watch requires date adjusting once every four years due to Leap Day.
