Multi-functional electronic watch

摘要

A multifunctional wrist watch combining the functions of time-indication with other functions, for example a calculator. The watch has a glass in which pick-ups are provided for detecting the passage of a finger of a user over the surface of the glass and recognition circuits for converting the trace detected into a logic signal for processing by a calculator circuit provided in the watch case. The output of the calculator is then displayed by the electro-optical display on the watch. The detection and recognition facility may also be utilized for correction of the date and time settings of the watch.
