Initially launched in 2012, the Rolex Sky-Dweller was presented by the firm as their first wristwatch with two time zones. Although many would argue that it was the GMT-Master that deserves the title, the Sky-Dweller operates in a different manner. Whilst the GMT-Master displays its second time zone on the 24-Hour rotating bezel, the Sky-Dweller displays its second time zone on the dial using a second 24-Hour disc on the center of the dial with a red triangle depicting the hour. The outer ring displays 12 apertures that indicate the month with a rotating bezel that determines the crown position. Through tremendous research and design with 11 new patents to protect its feature, Rolex was able to achieve this complex yet highly practical complication that would be one of the most sought after timepieces after its launch.

The present example in white gold fitted with a silvery white dial is presented in excellent overall condition and still bearing its factory protective stickers on the case and is further charmed by the complete set of accessories.
