Abstract

The invention provides a rechargeable electronic timepiece that restarts the operation of a clock circuit by inputting a power source, thereby securely confirming the clock operation. The electronic timepiece includes a first power source (), a clock circuit () connected to the first power source, a power source input detecting circuit () for detecting an input of a second power source (), a switch circuit () for connecting the first power source and the second power source, and a control circuit () for controlling the switch circuit to connect the first power source and the second power source so that the first power source is charged by the second power source thereby operating the clock circuit when the power source input detecting circuit detects an input of the second power source.
