The Sky-Dweller is powered by the Calibre 9001. It is a movement entirely developed and manufactured by Rolex. With multiple patents filed, this mechanical, self-winding movement is one of the most complex calibres created by the brand. Its architecture, manufacturing and innovative features make it exceptionally precise and reliable.The Rolex has a blue hairspring manufactured by Rolex in an exclusive paramagnetic alloy that makes it up to 10 times more precise than a traditional hairspring in case of shocks. The blue is equipped with a Rolex overcoil, ensuring the calibre’s regularity in any position. The oscillator is fitted on the Rolex-designed and -patented high-performance shock absorbers, increasing the movement’s shock resistance. The Calibre 9001 is equipped with a self-winding module via a Perpetual rotor and offers a power reserve of approximately 72 hours.
The Sky-Dweller is fitted with an Oysterflex bracelet, which singularly combines the robustness and reliability of a metal bracelet with the flexibility, comfort and aesthetics of an elastomer strap. Developed and patented by Rolex, this innovative bracelet is made up of flexible metal blades manufactured from a titanium and nickel alloy. The blades are overmoulded with high-performance black elastomer, a material that is particularly resistant to environmental effects and very durable. For enhanced comfort, the inside of the Oysterflex bracelet is equipped with longitudinal cushions.
The Oysterflex bracelet features a folding in 18 carat yellow gold, designed and patented by Rolex. In addition, it features the Rolex extension system, also developed and patented by the brand. This particularly inventive mechanism comprises a rack located under the clasp cover and a toothed sliding link that locks into the chosen notch. 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, and without tools, up to some 15 mm.
Like all Rolex watches, the Sky-Dweller carries the certification. These certification tests apply to the fully assembled watch, after casing 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, or more than twice that required of an official chronometer.
