Introduced in 2012, the Oyster Perpetual Sky-Dweller stands as one of the most complex watches in the Rolex catalog. It incorporates an annual calendar, which displays the month via apertures near the hour markers, alongside a second time zone shown on an off-center 24-hour disc. The fluted bezel acts as a control interface with three settings, allowing the wearer to adjust the date, local time, and reference time using only the crown.
