First launched in 2012, the Rolex Oyster Perpetual Sky-Dweller is the company's most complicated offering, with the ability to display two time zones at the same time. Local time, and the date, are in the standard Rolex format, whereas off-set from the dial centre is a 24-hour disc indicated to by a fixed inverted triangle.

This 24-hour display allows the wearer to keep track of day and night, whilst the current calendar month is indicated via one of the 12 apertures located beyond the hour indexes.

The 18 ct yellow gold and Everose gold versions of the Sky-Dweller are now available with an Oysterflex bracelet. This model is the first in the Classic category to include this innovative bracelet made of high-performance elastomer.
