Abstract

PURPOSE:To achieve the improvement in the operating characteristic and multifunctioning of the watch by unitizing keyboard switches so as to make possible removing from the watch body, exchanging the same and using the same as a watch having another function. CONSTITUTION:A keyboard switch unit 3a for calculation function which is readily removable from a watch body 1 is set in the watch body 1 which has a time display function, stopwatch function, memory function and culculation function. Register keys 4a and function keys 4b necessary for caulation function are disposed to the keyboard 3a for calculation function. A function discrimination detecting pin 5 makes contact to the function discrimination terminal 6 fixed to a circuit substrate 1a being a part of the watch body, by which the watch function is automatically set to the calculation function. The keyboard switches units for other functions are also able to provide respectively functions by setting to the watch body.
