Abstract

A microcomputer used in the multi-function watch comprises, in addition to its conventional circuits such as the program memory 1, the data memory 7 and the arithmetic and logic unit 6, a counter 13 with a counting capacity of 100. The counter can be set in operation and stopped by instructions forming part of a manually triggered program of the microcomputer. When it is operating, it counts pulses M1 of a frequency of 100 Hz which are supplied by the time base 10, 11 of the watch. When it reaches its maximum capacity, it is reset to zero and produces a chronographic time base signal T which sets the microcomputer in operation. This microcomputer then carries out a program which processes and causes display of the data relating to seconds, minutes and hours of chronographic time, which are stored in the data memory 7. Data relative to hundredths of a second of the chronographic time are given by the content of the counter and are processed and displayed only at the end of the operation of measuring the chronographic time.
