Rolex Certified Pre-OwnedSky-Dweller 2017, 42 mm, Rose Gold326935

An elegant watch for world travellers, 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.
