ROLEX

The Oyster Perpetual Sky-Dweller in Yellow Rolesor with a black 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 fixed inverted red triangle on the dial points to the chosen reference time – the time at home or at the traveller’s usual workplace – on the off-centre 24-hour disc. At a glance, this 24-hour display clearly distinguishes daytime hours from night-time hours in the other time zone. The dials now feature rectangular index hour markers and longer hands, as well as a Chromalight display with long-lasting luminescence, which enhances legibility.

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.
