The Rolex Sky-Dweller one of the most complicated models developed by Rolex, was presented at Baselworld 2012. A watch designed for globetrotters, the Sky-Dweller is a functional travel companion with a second-time zone, annual calendar, and a unique “Ring Command” bezel to set the functions. What sets the Sky-Dweller apart from so many GMT watches is its deceptively simple display made possible by an extremely complex movement protected by no less than 11 patents. Unlike the GMT-Master originally designed for Pan Am pilots, the Sky-Dweller is dressier and targeted at high-flying travelers.

The display of the Sky-Dweller is highly intuitive: local time is displayed with the 3 central hands; the second time zone or reference time is displayed on a rotating 24-hour disc in the center of the dial and indicated by an inverted red triangle; the date is displayed at 3 o’clock under a classic Cyclops lens; the month is arranged in 12 small apertures on the periphery of the dial at the tip of the indices which change from to white to red accordingly. The annual calendar automatically differentiates between 30 and 31-day months, meaning that only one adjustment is required a year, on 1 March.
