The Rolex Oyster Perpetual Sky-Dweller, launched in 2012, remains among the brand's most complex watches, combining an annual calendar with a second time zone display. Months are shown via apertures at the hour markers, while a 24-hour disc at 6 o'clock indicates the secondary time. The fluted bezel serves as a selector for the crown, simplifying adjustments for the date and time. This yellow gold model on an alligator strap was introduced in 2014.
