Abstract: A timepiece includes a micro control unit, to which a display unit, a timekeeping unit, a sound emitting mechanism, and a handwriting input unit are connected. The handwriting input unit is formed of a carbon powder layer, a duplicating layer, and a sensing circuit layer. Numerical characters indicating an alarm time may be directly handwritten on the handwriting input unit and identified by the sensing circuit layer, so that a signal is sent from the handwriting input unit to the micro control unit. When the timekeeping unit reaches at a time matching with the handwritten input alarm time, the micro control unit sends a signal to the sound emitting mechanism for the same to emit a sound. Therefore, a user may quickly and conveniently complete an alarm set on the timepiece.
