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.

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.

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.
