Abstract

This programming arrangement for a non-volatile memory incorporated in the inner circuit of a timepiece for adjusting the frequency of the time base thereof includes a support provided with a connector to be plugged in in place of the energy cell. The rate of division of the frequency divider is adjusted by the introduction into the memory of a number k representative of the frequency difference between the time base frequency and a standard frequency. To effect this the arrangement comprises an electronic circuit external to the timepiece and which is coupled thereto by the connector. The electronic circuit introduces the number k into certain predetermined stages of the divider. When such number k is thus introduced the state of such stages is blocked by the inner circuit of the timepiece such state then being transferred into the non-volatile memory.
