The charismatic and highly-technical Rolex Sky-Dweller is the perfect combination of style and functionality, and represents the most complicated watch currently produced by Rolex. The Sky-Dweller functions include the ability to read the time across two timezones, and an advanced annual calendar that can automatically decipher a 30, from a 31 day month. This stunning unworn 326934 model comes complete with box, papers and benefits from the remainder of the manufacturers international warranty.
