Abstract
There is disclosed an integral instrument providing timekeeping and display with calculator functions and display accomplished by means of a keyboard assembly mounted on the watch casing and adapted to be worn about a user's wrist. Included is time sharing circuitry to enable common display drivers for the timekeeping and calculating modes as well as power sharing circuitry to enable the use of inexpensive and reliable P-MOS circuitry in the calculator mode without constantly dissipating power. A time-zone setting circuit utilizes logic circuitry to automatically enable the user to change time by direct access to the existing keyboard assembly.
