Abstract
An electronic watch including an exterior case including an opening, a crystal disposed in the opening, an hour hand and a minute hand that indicate the time of day, a dial including an indicium, a pressure sensor configured to measure a pressure, and a controller configured to determine a water depth based on the output from the pressure sensor, indicate the water depth with the hour hand, and indicate an elapsed time with the minute hand, the elapsed time being time elapsed after the predetermined water depth value is exceeded.
Claims6
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.
