Abstract

PURPOSE: To provide an electronic timepiece, which transmits logic processing condition to the outside by the use of electrowave or acoustic signal, including electric field, magnetic field or other that can be received by a suitable instrument, whereby measurement of incremental rate can be facilitated on timepieces having similar logics, and accuracy of the measurement can be improved.
