CALIBRE 9002
The Sky-Dweller is driven by calibre 9002, a movement entirely developed and manufactured by Rolex. Released in 2023, it was introduced on the model the same year and exclusively equips this watch. A distillation of technology, this self-winding mechanical movement delivers outstanding performance, particularly 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 this movement extends to approximately 72 hours.
