PURPOSE:To obtain an electronic timepiece with a hydrobarometer which is extremely convenient for a user by forming the timepiece in such a manner as to store the max. water depth value and to simultaneously store the data together therewith. CONSTITUTION:A display control circuit 10, selects and outputs the water depth information PC from a water depth measuring circuit 6 as display information RX and displays the water depth value on a display device 12 via a decoder driver 11 when the circuit 6 is put into an operation state. A comparator circuit 8 compares the water depth information PC and the max. water depth value memory information PD inputted thereto from a max. water depth value memory circuit 7 and outputs a max. water depth value rewrite signal PE as an H level when the information PC is larger. The circuit 7 stores the information PC as the fresh max. water depth value by the signal PE and a clock memory circuit 4 stores the clock information PA of that time. The timepiece with the hydrobarometer which is extremely convenient for the user is thereby obtd. |
