Anyone know what is going on with the ZO 342 movement and ZO 9100 that zenith released a few years ago (2017/2018) with their Defy Lab/inventor watches? it runs at 15Hz & 18Hz /108,000vph 129,600vph respectively. They use a silicon based compliant mechanism for the oscillator which uses less energy and allows the high oscillation rate.
