The Oyster Perpetual Sky-Dweller in Oystersteel and white gold with a bright blue dial and an Oyster bracelet.

This distinctive watch is characterized by its second time zone display on an off-centre disc on the dial. Furthermore, its innovative system for setting the functions, using the rotatable Ring Command bezel, is unique to Rolex.

A deep red rectangle in one of the 12 windows around the dial indicated the current month, a striking characteristic of the Saros annual calendar. This ingenious mechanism simplifies life for the wearer of the watch, who no longer needs to think about adjusting the date at the end of a 30-day month. The annual calendar displays the correct date through the year. Only one adjustment is needed – on 1 March (February having only 28 or 29 days). The date is connected to local time and automatically changes according to the traveller’s local time zone.
