Specially developed for the Sky-Dweller, the patented Saros annual calendar is a key element in the model’s identity. The name of this mechanism, with its innovative design, is inspired by the Greek term denoting the cycle of lunar and solar eclipses.
Calibre 7135’s oscillator features a balance staff whose material and manufacture presented a significant challenge, a balance wheel made from optimized brass, and a silicon Syloxi hairspring. The patented balance staff is made from a new high-technology ceramic exclusive to Rolex and is shaped by laser – a first for the brand. Optimized Paraflex shock absorbers give the movement heightened shock resistance in any position. Finally, thanks to the various materials used to produce the oscillator’s components, it is able to withstand strong magnetic fields.
