Revolutionary movement featuring a monolithic silicon oscillator that replaces the traditional balance wheel, hairspring, and lever escapement with a single component. The ZO designation stands for 'Zenith Oscillator' and 342 refers to the number of years since Huygens invented the sprung balance in 1675. Operates at an extraordinary 15Hz (108,000 vph) with extremely low amplitude of only ±6 degrees versus 300 degrees for traditional balance wheels. Achieves accuracy within 0.3 seconds per day. The oscillator is 0.5mm thick with parts thinner than a human hair. Insensitive to temperature, gravity, and magnetic fields up to 1,100 Gauss. Only 10 pieces produced in the Aeronith-cased Defy Lab watch.
