作が可能となる。In this state, when the switch SS is operated, the 5
The start signal ST output from AP8 becomes "Hm level. Therefore, the output signal Si of AND gate 9 becomes "Hm level.
" level, and the water pressure measurement circuit 5 becomes operational and outputs water depth information Ps. However, in the state where diving has not yet been performed, the water depth information Ps is ps<i meters, so the water pressure measurement circuit 5 is not controlled by the water pressure detection circuit 6. Since the signal CC remains at the "Hm" level and the AND gates 7a and 8a continue to be in the ON state, both operation signals from the operation of the switches KS and SS can be received.6 Therefore, in this state, the carrier operates switch KS again, function selection circuit 7
operates and returns to the clock function. When the wearer starts diving from this state, the water depth is displayed on the display device 12 each time the water pressure sensor 4 detects the water depth. After the dive starts, the water depth information PS becomes Ps≧
When the water pressure reaches 1 meter, the water pressure detection circuit 6 sets the control signal CC to "L" level, so the AND gates 7a and 8a become O.
The FF state is entered, and the passage of operation signals caused by operating the switches KS and SS is prohibited. In this state, the water depth information is always displayed because the switch KS does not return to the clock function. Then, when the wearer finishes diving and comes to the surface, the water depth i[aPs decreases and the water depth information Ps changes to Psi! When the voltage reaches m, the control signal CC becomes m)+m level, and the AND gates 7a and 8a become O.
It becomes N state, and it becomes possible to switch to the limit clock function state in which the operation signal by operating the switches KS and SS can be passed.

に大なる効果がある。As is clear from the above explanation, according to the present invention, the function selection switch is configured to be prohibited when the water pressure exceeds a certain level of water depth. This has a great effect on the commercialization of electronic watches with depth gauges that allow safe diving, since depth information is always displayed without time information being displayed.
