Mastering travel time

Elegant and technically sophisticated, the Oyster Perpetual Sky-Dweller was designed for those continually travelling the globe. Featuring the Saros annual calendar and Ring Command system, it simultaneously indicates two time zones, as well as the date and month, and allows them to be adjusted with one simple gesture.

Since its creation in 2012, the Sky-Dweller has been aimed at those who see the world as a single territory, without borders. It allows travellers to avoid the pitfalls of time differences and always stay one step ahead.


The Sky-Dweller simultaneously displays the time in a second time zone as well as the local time, which is indicated by central hands. This second time zone – or reference time – is indicated by a highly legible, small triangle with a red silhouette on a 24-hour graduated rotating disc. A signature element of the model, this off-centre disc makes it possible to unequivocally distinguish between daytime and night-time hours: an invaluable asset for someone travelling to the other side of the world.

Innovative and intuitive annual calendar

Specially developed for the Sky-Dweller, the patented Saros annual calendar is a key element in the model’s identity. The name of this mechanism, with its innovative design, is inspired by the Greek term denoting the cycle of lunar and solar eclipses.

The Saros calendar automatically differentiates between 30-day and 31-day months. It therefore requires only one manual date adjustment a year, when February turns to March. It is intuitive and simple to read. The current month is indicated in red in one of the dozen windows that punctuate the hour markers around the circumference of the dial.

The watchmaking innovation relies on two-gear ratios and only four-gear wheels added to Rolex’s instantaneous date calendar. This elementary structure gives the Saros annual calendar excellent reliability.

Ring Command system: time under control

Developed by Rolex, the patented Ring Command system is an innovative mechanism of interaction between the rotatable bezel, winding crown and movement. It allows the Sky-Dweller’s different functions to be selected easily, quickly and securely, before adjusting them with the winding crown.

By turning the fluted bezel counterclockwise – the profile of which is accentuated to make it easier to handle – the wearer chooses the indication that they wish to set. First notch: date and month. Second notch: local time. Third notch: reference time.


Whether a golfer, sailor or equestrian rider, criss-crossing the globe, they must always be ready, whatever the destination or distance travelled.

Spanish golfer Jon Rahm, Brazilian skipper Robert Scheidt and American show jumper Kent Farrington are among the Rolex Testimonees who have adopted the Sky-Dweller.
