Oyster Perpetual Sky-Dweller
TO THE ULTIMATE AND BEYOND
With its two time zones and annual Saros calendar, the Sky-Dweller is an elegant and trusted companion for world travellers. The range has been updated with numerous enhancements illustrating the role that excellence plays even in the tiniest details.
Rolex restyles its Oyster Perpetual Sky-Dweller, recognised for its ease of use and modern design, by introducing aesthetic and technical enhancements.
This watch for world travellers is offered, in particular, in an 18 ct white gold version on an Oysterflex bracelet. It is the first time that a version of the Sky-Dweller combines this precious metal, which is returning to the range, with the black elastomer bracelet.
The other two variants unveiled introduce two new dial colours for the model. The white Rolesor version (combining Oystersteel and white gold), fitted on an Oyster bracelet, features a mint green dial, a colour reserved until now for the Datejust. And the variant fashioned in 18 ct Everose gold is endowed with a blue-green dial. A subtle alliance of two tones, the latter is available only on the reference presented, complemented by an Oyster bracelet.
The Sky-Dweller is now equipped with calibre 9002. An evolution of calibre 9001, this new movement includes some of the major innovations that Rolex has brought to its movements, including the Chronergy escapement. Calibre 9002 enables the Sky-Dweller to display the date and the month, as well as an additional time zone in 24-hour format, and the hours, minutes and seconds.
Like all Rolex watches, the Sky-Dweller carries the Superlative Chronometer certification, which ensures excellent performance on the wrist.
A wealth of expertise
An elegant watch for frequent travellers, the Sky-Dweller displays the time in two time zones simultaneously and has an annual calendar. The reference time is displayed in 24-hour format via an off-centre disc, and local time is read using the conventional centre hands. The annual calendar, named Saros, automatically differentiates between 30- and 31-day months. It is operated by a patented mechanism and stands out for its innovative display: the months of the year are shown in 12 apertures around the circumference of the dial, beyond the index hour marker – the current month being shown in red. The instantaneous date change is linked to the local time.
The Sky-Dweller includes the Ring Command system, an interface between the rotatable bezel, winding crown and movement that allows the wearer to select and set the timepiece’s functions one by one, easily, quickly and securely.
Rolesor, a marriage of gold and steel
Rolesor, the combination of gold and Oystersteel on a Rolex watch, has been a signature feature of the brand since 1933, when the name was registered. It is a meeting of two metals: one, noble and precious, attractive for its lustre and stability; the other, highly resistant to corrosion, assuring strength and reliability. All of these qualities mirror the elegance and performance that come together in a Rolex watch.
On the new Sky-Dweller offered in the white Rolesor version, the bezel is in white gold; the winding crown, middle case, case back and bracelet are in Oystersteel.
Perpetual calibre 9002
The new-generation Sky-Dweller is equipped with calibre 9002, unveiled this year. A distillation of technology, this self-winding mechanical movement – a derivation of calibre 9001, one of the most complex movements designed by Rolex and which had driven the model since its launch in 2012 – delivers outstanding performance in terms of precision, power reserve, convenience and reliability.
Calibre 9002 incorporates the patented Chronergy escapement, which combines high energy efficiency with great dependability. Made of nickel-phosphorus, this escapement is resistant to strong magnetic fields. The movement is fitted with a blue Parachrom hairspring, manufactured by Rolex in a paramagnetic alloy. The hairspring offers great stability in the face of temperature variations as well as high resistance to shocks. It is equipped with a Rolex overcoil, ensuring the calibre’s regularity in any position. The oscillator is mounted on the Rolex-designed, patented high performance Paraflex shock absorbers, increasing the movement’s shock resistance. The oscillating weight is fitted with an optimized ball bearing.
Calibre 9002 is equipped with a self-winding system via a Perpetual rotor. Thanks to its barrel architecture and the escapement’s superior efficiency, the power reserve of calibre 9002 extends to approximately 72 hours.
The Oyster case,
symbol of waterproofness
A paragon of robustness and elegance, the 42 mm Oyster case of the new-generation Sky-Dweller is guaranteed waterproof to a depth of 100 metres (330 feet). The middle case of the versions presented is crafted from a solid block of Oystersteel, or 18 ct white or Everose gold. Its case back, edged with fine fluting, is hermetically screwed down with a special tool that allows only Rolex watchmakers to access the movement. The Twinlock winding crown, fitted with a double waterproofness system, screws down securely against the case. The crystal, which features a Cyclops lens at 3 o’clock for easy reading of the date, is made of virtually scratchproof sapphire and benefits from an anti-reflective coating. The waterproof Oyster case provides optimal protection for the movement it houses.
Oysterflex and Oyster bracelets
Among the versions of the new-generation Sky-Dweller presented this year, the watch in 18 ct white gold sporting a bright black dial is fitted on an Oysterflex bracelet. Developed by Rolex and patented, this innovative bracelet is made up of two flexible, curved metal blades – one for each of the sections – overmoulded with high-performance black elastomer.
The new white Rolesor version (combining Oystersteel and white gold), adorned with a mint green dial, as well as the 18 ct Everose gold watch, with a blue-green dial, are fitted on an Oyster bra celet. Developed at the end of the 1930s, this three-piece link bracelet remains the most universal in the Oyster Perpetual collection and is known for its robustness.
The Oysterflex bracelet and the Oyster bracelet of the Sky-Dweller are both equipped with a folding Oysterclasp. The Oysterflex bracelet is furnished with the Rolex Glidelock extension system. Developed by the brand and patented, this inventive mechanism with a rack located under the clasp cover enables fine adjustment of the bracelet length, without the need for tools. The Rolex Glidelock on the Oysterflex bracelet has six notches of approximately 2.5 mm, allowing the length of the bracelet to be adjusted easily up to some 15 mm. For its part, the Oyster bracelet of the Sky-Dweller features the Easylink comfort extension link, developed by the brand, which allows the wearer to easily increase the brace let length by approximately 5 mm. On the version in 18 ct Everose gold, the bracelet also includes patented ceramic inserts – designed by Rolex – inside the links to enhance its flexibility on the wrist and its longevity.
Superlative Chronometer Certification
Like all Rolex watches, the Oyster Perpetual Sky-Dweller is covered by the Superlative Chronometer certification redefined by Rolex in 2015. This designation testifies that every watch leaving the brand’s workshops has successfully undergone a series of tests conducted by Rolex in its own laboratories according to its own criteria, following the official certification of the movements by the Swiss Official Chronometer Testing Institute (COSC). The in-house certification tests apply to the fully assembled watch, after cas - ing the movement, guaranteeing superlative performance on the wrist in terms of precision, power reserve, waterproofness and self-winding. The precision of a Rolex Superlative Chronometer is of the order of −2/+2 seconds per day – the rate deviation tolerated by the brand for a finished watch is significantly smaller than that accepted by COSC for official certification of the movement alone.
The Superlative Chronometer status is symbolised by the green seal that comes with every Rolex watch and is coupled with an international five-year guarantee.
