Rolex is introducing new versions of the Oyster Perpetual Sky-Dweller, its classic watch for world travellers, for the first time in a choice of yellow Rolesor or white Rolesor versions – combining 904L steel and 18 ct yellow or white gold.

The dials now feature rectangular index hour markers and longer hands, as well as a Chromalight display with long-lasting luminescence, which enhances legibility.

A technological masterpiece protected by 11 patents, the Sky-Dweller provides, in an unprecedented and highly original way, the information global travellers need to easily keep track of time.

It includes a dual time zone, with local time read via centre hands and a reference time display in a 24-hour format read via a rotating off-centre disc on the dial; a particularly innovative annual calendar named Saros – after the astronomical phenomenon of the same name – that requires only one date adjustment a year, when the month changes from February to March; and a month display by means of 12 apertures around the circumference of the dial.

To set its functions quickly and easily, the Sky-Dweller is also equipped with an innovative patented interface: the rotatable Ring Command bezel.
