summary

A technological masterpiece protected by 14 patents, the Oyster Perpetual Sky-Dweller provides the information global travellers need to keep track of time at a glance. Launched in 2012, the Sky-Dweller is a compelling timepiece of revolutionary design that blends to perfection mechanical sophistication and ease of use.

3Introduction

The original design of the dual time zone display and the discreet annual calendar endows the Sky-Dweller with an exclusive aesthetic identity, singling it out as the global traveller’s watch. The rotatable fluted bezel and the 42 mm case crafted from a solid block of 18 ct gold are distinguished hallmarks of Rolex elegance.

Thanks to sophisticated engineering, the Sky-Dweller is intuitive to read and simple to use. Local time is displayed by the traditional centre hands and the off-centre rotating disc with 24 hour markers shows the chosen reference time on the dial. The Cyclops lens magnifies the date for easy reading while the current month is displayed in one of 12 discreet apertures around the circumference of the dial. This annual calendar requires only one date adjustment a year, in February. The innovative fluted Ring Command bezel completes the interface, allowing the global traveller to easily select each individual function he needs to set.

Function of the Sky-Dweller

The rotatable Ring Command bezel interacts with the movement to allow the global traveller to easily access the watch functions that need to be set. The bezel can be turned to any 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 which consists of no fewer than 60 components, the product of state-of-the-art watchmaking and micromechanical expertise. Such innovation epitomizes Rolex’s mastery of the design and manufacture of all the essential components of the watch.

second time zoneA fixed inverted red triangle on the dial points to the chosen reference time – the time at home or at the traveller’s usual workplace – on the off-centre 24-hour disc. At a glance, this 24-hour display clearly distinguishes daytime hours from night-time hours in the other time zone (for example, 10 p.m. versus 10 a.m.). At any moment and in any location, the global traveller knows if it is an appropriate time to contact colleagues or loved ones on the other side of the world.

The conventional centre hour, minute and seconds hands indicate local time. It can be changed quickly and effortlessly without affecting the precision of the traveller’s timekeeping thanks to the Rolex jumping hour hand. The hour hand is adjusted independently in one-hour increments, either forwards and backwards, leaving the minute and seconds hands, as well as the reference time, unchanged. The date change is linked to the local time and occurs within a few milliseconds at midnight. The date displayed in the aperture is always the current date at the traveller’s location.

discreet month aperturesThe months of the year are indicated in 12 discreet apertures around the circumference of the dial: January at 1 o’clock, February at 2 o’clock, and so on. The current month is identified in a contrasting colour.

revolutionary annual calendarInspired by the Saros, an astronomical phenomenon, the Sky-Dweller’s date only requires one adjustment a year – on the 1st of March, February having only 28 or 29 days. The ingenuity of the mechanical system developed by Rolex lies in its simple and systematic handling of the irregular occurrence of 30- and 31-day months, allowing it to display the correct date throughout the rest of the year. With the Saros system, Rolex added only two gear ratios and four gear wheels to its traditional instantaneous date calendar. Such simplicity ensures a peerlessly robust and reliable annual calendar function.

10Function

Function of the Sky-Dwellersaros systemThe Saros system is designed around a fixed planetary gear wheel (equivalent to the Sun) at the centre of the movement. A satellite wheel (whose centre represents the Earth) engages with the planetary wheel and rotates, orbiting the planetary wheel in one month, driven by the date disc. The satellite wheel is fitted with four fingers (the Moon) for the four 30-day months (April, June, September and November). These fingers reach a specific position at the end of each month, and force the date to jump two days only in 30-day months. After one year, the system realigns to its original position, having completed a full Saros cycle.

11Function

saros: planetary inspirationAt the heart of the Sky-Dweller movement lies a revolutionary planetary mechanism inspired by the cyclical alignment of Sun, Earth and Moon.

The Greek term Saros has been used since antiquity to designate an astronomical cycle of alignment patterns between the Sun, the Earth and the Moon which governs the recurrence of eclipses. This phenomenon inspired the design of the Sky-Dweller’s annual calendar mechanism.

Features

When the Rolex Oyster first appeared in 1926, the fluted bezel had a functional purpose: it served to screw the bezel onto the case helping to ensure the waterproofness of the watch. It was, furthermore, identical to the fluting on the case back, which was also screwed onto the case for the same reason, using specific Rolex tools. Over time, the fluting became a purely aesthetic element, available only in 18 ct yellow, Everose or white gold on Datejust and Day-Date models. The fluted bezel is rotatable on the Sky-Dweller, where it has regained functionality to allow easy selection of watch functions. Fluting is a genuine Rolex signature feature, a mark of distinction.

13Features

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.

Unique feature

The four simple words Superlative Chronometer Officially Certified on a Rolex watch dial mean that the very movement inside the timepiece has endured 15 days and nights of testing by COSC (Contrôle Officiel Suisse des Chronomètres – Swiss Official Chronometer Testing Institute), an independent not-for-profit association.

To receive COSC certification as a Swiss chronometer, a watch must demonstrate extreme precision in a variety of positions and temperatures. Rolex is unique in the industry: this is the standard level of quality required of every Rolex wristwatch movement.
