Innovation for those who travel the world...
The first Rolex with a dual time-zone display and an annual calendar that marks the passage of the months.
1 — DUAL TIME ZONE
The two time zones are displayed simultaneously.
Local time is indicated by the conventional centre hour, minute and seconds hands. It can be set quickly and easily by means of a mechanism that allows the hour hand to be adjusted independently in one-hour increments both forwards and backwards. Neither the minute and seconds nor the reference time in the second time zone are affected. And, since the watch is not stopped, accuracy is preserved. Reference time in the traveller’s usual place of residence or work is read on a rotating off-centre disc. A fixed inverted red triangle points to the wearer’s chosen reference time. The disc’s 24-hour display allows travellers to clearly distinguish daytime hours from night-time hours in the distant time zone (for example, 10 p.m. versus 10 a.m.). The date change is linked to local time and occurs within a few milliseconds at midnight. So the date displayed in the aperture is always the current date in the wearer’s local time zone.
2 — ANNUAL CALENDAR
Deep red in one of 12 windows around the dial indicates the current month, a striking characteristic of the Saros annual calendar.
This ingenious mechanism simplifies life for the wearer of the watch, who no longer needs to think about adjusting the date at the end of a 30-day month. The annual calendar displays the correct date through the year. Only one adjustment is needed – on 1 March (February having only 28 or 29 days). The date is connected to local time and automatically changes according to the traveller’s local time zone.
3 — RING COMMAND BEZEL
As simple as one, two, three
Setting the Sky-Dweller’s three main functions is quick and easy. It can be done in any order, and both forwards and backwards, without restriction. Each function is accessed using the rotatable Ring Command bezel and adjusted with the winding crown, which has only one setting position. The operation is as simple as 1-2-3.
ROLEX CALIBRE 9001
The Sky-Dweller is equipped with calibre 9001, a self-winding mechanical movement entirely developed and manufactured by Rolex. Introduced in 2012, it is one of the most complex calibres ever created by Rolex watchmakers. Nonetheless, it is engineered to ensure simplicity of use: a selector wheel on the outside edge of the 9001 ensures the interaction of the movement and the bezel of the watch to set the Sky-Dweller’s functions. Like all Rolex Perpetual movements, the 9001 is a certified Swiss Chronometer, a designation reserved for high-precision watches that have successfully passed the Swiss Official Chronometer Testing Institute (COSC) tests. Its architecture, in common with all Oyster watch movements, makes it singularly reliable.
The Saros annual calendar
A revolutionary planetary mechanism inspired by the cyclical alignment of Sun, Earth and Moon lies in the heart of the Sky-Dweller. The Greek term saros has been used since antiquity to designate an astronomical cycle which governs the recurrence of eclipses.
The Sky-Dweller’s Saros annual calendar owes its high efficiency to a mechanism of revolutionary simplicity. Displaying the correct date through the year, this ingenious system patented by Rolex replicates the irregular occurrence of 30- and 31-day months using only four additional gear wheels.
The Ring Command bezel
The rotatable Ring Command bezel interacts with the movement to allow the global traveller to easily access the watch functions that need setting. The bezel can be turned to one of three positions to select the date, local time or reference time. The selected function can then be rapidly adjusted in either direction using the winding crown. This intuitive interface is based on a complex mechanical module with no fewer than 60 components, the product of state-of-the-art watchmaking and advanced micromechanics. Such innovation epitomizes Rolex's in-house mastery of the design and manufacture of all the essential components of the watch.
