The Sky-Dweller, designed for those constantly travelling the globe.

Launched in 2012, the Oyster Perpetual Sky-Dweller features a dual time
zone and an annual calendar. Known as Saros, the calendar is driven by a
patented mechanism called the Ring Command and displays the month by
means of 12 apertures around the circumference of the dial – the current
month is shown in a contrasting colour. A compelling blend of technical
sophistication and ease of use, the Sky-Dweller is the result of Rolex’s
unique culture of innovation.
