The Rolex Sky-Dweller ($14,400 in OysterSteel; $17,150 steel and yellow gold; $48,850 for gold) is an annual calendar and dual time zone watch with an unusual display. It has a cutaway dial with small rectangular apertures at each hour to indicate the month (in red): January is represented by 1 o’clock, February by 2 o’clock, and so on. The date is connected to the local time, which is displayed via the center hands. The red arrow on the dial just under the 12 o’clock position points to a 24-hour number on the off-centered rotating disk below, which is the home time. All can be adjusted with a bezel-operated control ring that Rolex calls Ring Command. It contains the 9001, Rolex’s most complex caliber, with seven patents.
