This Rolex Sky-Dweller features dual time zones, inlaid in a 42mm oystersteel case and white gold fluted bezel surrounding a white dial with luminous hour markers. The Ring Command bezel can be rotated to select the date, the local time and the reference time, which can then be adjusted in either direction using the winding crown. It is housed on a white gold and stainless steel oyster bracelet with three-piece links and folding-clasp.
