The Rolex Oyster Perpetual Sky-Dweller was introduced in 2012 and is one of Rolex’ most complicated watches to date. It features an annual calendar and a second time zone function. The former has a regular date display, while the month is displayed through apertures by the hour markers. The latter is indicated through an off-centre 24h disc at 6 o’clock. The well-known fluted bezel functions as sort of a gear box with three positions, enabling the user to set the date, local time and second time zone through one single position on the crown.The present version, with yellow gold case and alligator strap, was added to the collection in 2014.
