The Rolex Sky-Dweller is the quintessential watch for global travelers. It is one of Rolex's most complicated models, masterfully combining two major complications controlled by a revolutionary interface.
Key Highlights:
Dual Time Zone:
Local Time: Displayed by the traditional central hour, minute, and second hands.
Reference Time (Home Time): Indicated on an off-center, 24-hour rotating disc. A fixed red triangle points to the wearer's reference time, making a clear distinction between day and night hours at home.
"Saros" Annual Calendar:
This is an intelligent calendar mechanism that automatically differentiates between 30-day and 31-day months.
It requires adjustment only once per year, on March 1st (to account for February's 28 or 29 days).
The months are discreetly displayed via 12 small apertures located around the circumference of the dial, outside the hour markers (e.g., 1 o'clock for January, 2 o'clock for February).
"Ring Command" Bezel:
This is the watch's genius feature. It is not a standard bezel.
By rotating the fluted bezel (which has 3 positions), the wearer can select which function to set (Date, Local Time, or Reference Time). All adjustments are then made simply by turning the winding crown.
Design: The Sky-Dweller features a 42mm case, giving it a strong presence on the wrist. It is available in various materials, including Oystersteel (typically with a white gold bezel), Rolesor (steel and gold), and solid gold (yellow or Everose gold).
