Rolex added two new dial variants to the Sky-Dweller collection in 2023, as well as a new version fitted with an Oysterflex strap.

The Sky-Dweller was first introduced in 2012, and retains the same case dimensions as existing models at 42 mm x 13.8 mm, with a 22 mm lug width. The dial functions and layout also remain the same as before.

What’s new is the addition to the two new dial colors, mint green (previously reserved for the Datejust) and blue-green, and the white gold model on an Oysterflex strap for the first time. The only other change to the Sky-Dweller is the movement, which has been upgraded from the original caliber 9001 to the new caliber 9002.

The Sky-Dweller remains Rolex’s most complicated timepiece, with local time via three conventional, centrally mounted hands, including the ability to the rapid independent setting of the hour hand. The second time zone (home/reference time) is displayed via a 24-hour disc in the center of the dial. The date display at 3 o’clock has a cyclops magnifier and can be set instantaneously in either direction and is connected to the local time. Additionally, the Saros annual calendar function allows for the date to remain correct for all months with 30/31 days, though requires a manual adjustment for February.  There are 12 apertures around the circumference of the dial that display the 12 months of the year, with a red indicator for the current month.

One of the functions that make the Sky-Dweller Rolex’s most complicated is the Rolex Ring command system, which is controlled by the fluted bidirectional rotatable bezel that acts as an interface between the bezel and the crown and that allows the wearer to select and set the timepiece’s functions one by one, with ease.

While the evolution of the caliber 9001 to the new caliber 9002 is notable, the new movement does not offer any new functionality or enhanced output, instead, it receives Rolex’s patented anti-magnetic nickel-phosphorus Chronergy escapement which combines high energy efficiency and dependability. The oscillating weight has also been upgraded, though no additional performance benefits have been listed by Rolex. Aside from these two changes, the caliber 9002 retains the 9001’s existing 4Hz frequency, automatic winding,  traversing balance bring, free-sprung balance wheel, blue Parachrom hairspring, Paraflex shock absorbers, and the oscillating weight is fitted with an optimized ball bearing. The power reserve of 72 hours remains unchanged.

Whether the Sky-Dweller is fitted with an Oysterflex strap or an Oyster bracelet, each is equipped with a folding Oysterclasp with a Glidelock system. The Oyster bracelet can be extended 5 mm for comfort whereas the Oysterflex can be adjusted up to 15 mm (in 2.5 mm increments).
