ABSTRACT:
A manual set operation is described for a timepiece where a single switch is used to select categories and values for setting timekeeping quantities. The timepiece is implemented using a CMOS microcontroller integrated circuit and employs a matrix liquid crystal display to display time and calendar information one character at a time, in a slide-show manner.
