1. An electronic watch comprising:
a case including an opening;
a crystal disposed at the opening;
a first hand and a second hand that indicate a time;
a dial including an indicium;
a water detection sensor configured to detect a first state in which the electronic watch enters into water and a second state in which the electronic watch exits from the water;
a pressure sensor configured to measure a pressure; and
a controller configured to:
receive a first signal indicating the first state and a second signal indicating the second state;
supply power to the pressure sensor to cause the pressure sensor to measure the pressure in response to the first signal;
determine a water depth based on an output from the pressure sensor;
indicate the water depth with the first hand;
indicate, with the second hand, an elapsed time after a predetermined water depth value is exceeded; and
stop the supply of the power to the pressure sensor to cause the pressure sensor to stop the measurement of the pressure in response to the second signal.
