Abstract
An electronic timepiece having time indicating hands driven by a motor through a gear train, and having an analog-to-digital conversion system for time data comprising code disks rotated by the wheel train to provide hours and minutes information in digital coded form, together with means for converting this encoded digital information into digital signals representing hours and minutes information corresponding to the time information indicated by the hands and synchronized with the time indicated by the seconds hand of the timepiece.
