Abstract

PURPOSE:To add a function of a depth meter to an electronic watch by storing the oscillating frequency of a piezoelectric element driven by self-oscillation in a memory temporarily and by measuring the depth of water thereby. CONSTITUTION:The piezoelectric element 10 stuck to a back cover 1 is driven by a self-oscillation circuit 11 and the oscillated output waveform of a natural frequency varying in accordance with the pressure of the element 10 is impressed on a counter circuit 13 through a clipper circuit 12. When the count value of the circuit 13 is stored in a memory 14 by an instruction signal A sent through the intermediary of an outside switch, a reference value in the case of the measurement of the depth of water is set in the memory 14. And, when the content of counting of the counter 13 and the content of memory of the memory 14 are counted by a sum-difference counter 15, the depth of water corresponding to the water pressure is indicated in an indicating member 18 through the intermediary of a decoder 16 wherein a value of water depth is set beforehand, and of a driving circuit 17, etc. Thus, a watch thus constituted turns to be the electronic watch to which the function of depth meter is also added.
