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.
