ABSTRACT:
An apparatus is disclosed comprising an electronic wristwatch and a multifunction electronic calculator in a single wrist mountable case having a common display and keyboard. The watch portion of the watch/calculator includes time of day, calendar, stopwatch and alarm functions. Each of these functions can be controlled from the keyboard on the watch/calculator. The electronic calculator portion of the watch/calculator performs the four standard arithmetic functions: add, subtract, multiply and divide; and has an extra storage register. The calculator portion can perform calculations with scalar quantities entered via the keyboard or stored in the calculator as well as calculations with time interval and real time data from the watch portion. During the time that calculations are not being performed the calculator goes into a sleep or inactive mode in order to minimize the amount of battery power used by the watch/calculator.
