摘要： A time correction circuit for a timepiece with an electrochromic display which includes a timing circuit having counters counting time standard clock signals and for generating time display output signals, a time display circuit having an electrochromic display section displaying output signals from said counters, a correction mode changeover switch selectively switching between a time display mode and a time correction mode, a correcting circuit which works only when said correction mode changeover switch selects the correction mode to change the count in the counters, a writing and erasing control circuit for controlling the timing of the writing and the erasing of the electrochromic display section in response to the mode selected by the correction mode changeover switch and a correction pulse generating circuit for outputting time correction writing pulses of smaller pulse width than time correction writing and erasing pulses during the time display mode when the correction mode changeover switch selects the time correction mode to enable fast correction of the electrochromic display.
