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.Reference 326238-0009 was added to the collection in 2020. It features a Black dial and is fitted with an ‘Oysterflex’ rubber bracelet.
