Abstract

A method for controlling an electronic watch includes a first pointing hand, a first motor configured to move the first pointing hand, a second pointing hand, a second motor configured to move the second pointing hand, a pressure sensor configured to measure pressure, and a mode indication unit configured to indicate a mode, and when detecting start of diving based on a pressure measured by the pressure sensor, control is performed on the first motor and the second motor to indicate with the first pointing hand a water depth estimated from the pressure and indicate with the second pointing hand a time period of diving for which timing is started after detecting the start of diving, and when the water depth is indicated with the first pointing hand, with a plurality of modes with different indication resolutions being provided, the selected mode is indicated on the mode indication unit.

Dependent claims

A method for controlling an electronic watch, the method comprising:

when start of diving is detected based on a pressure measured by a pressure sensor, controlling a first motor to indicate with a first pointing hand a water depth estimated from the pressure;
controlling a second motor to indicate with a second pointing hand a time period of diving for which timing is started after detecting the start of diving;
selecting one mode from a plurality of modes with different indication resolutions, and controlling the first motor and the second motor based on the selected mode;
and
determining that the start of diving occurs when the water depth is equal to or greater than a predetermined threshold value,
wherein the plurality of modes with different indication resolutions include a first mode in which the indication resolution is first indication resolution, and a second mode in which the indication resolution is second indication resolution that is greater than the first indication resolution, and
the method further includes using a processor to determine, when the first mode is set and the water depth is equal to or greater than a first threshold value, that the start of diving has occurred, and
using the processor to determine, when the second mode is set and the water depth is equal to or greater than a second threshold value that is greater than the first threshold, that the start of diving occurs.
