With its new disruptive “Zenith Oscillator” control system, the brand with the guiding star is revolutionising mechanical watchmaking. High frequency, chronometric precision, reliability and stability: the oscillator developed and patented by the Manufacture replaces the traditional sprung balance used for more than three centuries! Featuring a single element (compared with 30 or so components of a standard regulating organ), this high-tech device equips the new DEFY Inventor. A case made of lightweight titanium and Aeronith – an innovative aluminium-polymer composite – teamed with an architectural design: through the DEFY Inventor, Zenith is (re)inventing the watchmaking of tomorrow, in an entirely independent manner.
