This is a guest post from HODINKEE, a watch blog that's sharing some highlights from Basel World 2012, the world's largest watch show, with us.
After all the hype, you are looking at what is (probably) the first live photos of the actual Rolex Sky-Dweller.
What it is is this: A Rolex in the Day-Date vein, but with a second timezone via an inner rotating disc and an annual calendar. A Rolex annual calendar? Yup!
The annual calendar display the month with an inconspicuous aperture above the associated hour (12 hours - 12 months, get it?) and the date is displayed in the typical way under the trademark Rolex cyclops window.
