This is an electronically controlled balance wheel watch. Timex added a quartz crystal which acts as a reference in much the same manner as it does in the Spring Drive. It doesn't directly affect the regulation but is instead used as a reference that is compared to the beat of the balance wheel. Differences are then fed to the balance to either speed it up or slow it down until the corrections are made.Correction; these movements were controlled by the quartz crystal...D'oh! I don't believe it was actually any better than standard quartz watches would become but it was bleeding edge at the time!
