Turning heads at Baselworld in 2012, the Rolex Sky-Dweller captured headlines for the manufacturer by stepping into the boundaries of complicated wristwatches. It was Rolex’s first and only contemporary calendar wristwatch since the 1950s. Reference 326939 ingeniously integrates the calendar functions within the 18k white gold fluted bezel. It can be rotated to move the date forward and backward, change the date, and jump hour the hands. The watch also has the option to set a second time zone via the 24 hour indicator. An 18k white gold bracelet adds to the robustness of the timepiece, making the Sky-Dweller an elegant wristwatch that is ready for on-the-go travel.
