According to various embodiments, a watch may be provided. The watch may include: a timing circuit configured to provide information about a current time; a smart watch circuit configured to provide smart watch functionality; a first battery configured to provide energy to the timing circuit; a second battery configured to provide energy to the smart watch circuit; and a communication circuit configured to provide communication between the timing circuit and the smart watch circuit; wherein the communication circuit includes a safety circuit configured to prevent leakage of current from the first battery to the second battery.

An electronic device comprises a body and a band being able to attach the body to a part of a human body. The body comprises first and second detectors and at least one processor. The first detector detects illuminance on an upper surface of the body. The second detector is located in a position distant from a position of the first detector in a short-side direction of the band and detects the illuminance on the upper surface of the body. The at least one processor executes predetermined processing if the at least one processor determines that at least one of first illuminance detected by the first detector and second illuminance detected by the second detector changes.

An electronic watch includes a power generating mechanism; a battery that is charged with power generated by the power generating mechanism; hands that include a second hand; a driving source that rotates the hands; a driving circuit that drives the driving source with power supplied by the battery; and a control circuit that controls the driving circuit. The control circuit executes a first stopping operation for stopping the driving circuit and the control circuit in a power saving mode for suppressing power consumption and when a first determination time elapses without any power being generated by the power generating mechanism. The control circuit executes a second stopping operation for stopping the driving circuit and the control circuit in the power saving mode and when a second determination time elapses while a voltage of the battery is at a level equal to or lower than a predetermined level.

An electronic device includes a memory; a first processor; a second processor for which power consumption is lower than power consumption of the first processor; a communicator that communicates with an external device; and a switch that switches a connection destination of the communicator to the first processor or the second processor. The second processor is configured to, in a case in which a condition for transitioning to a power suppression state that is an operating state in which power consumption is suppressed is satisfied, connect the communicator by the switch. The first processor is configured to, in a case in which a condition for transitioning to a normal state that is a normal operating state is satisfied, connect the communicator by the switch.

A watch or other type of portable electronic console that employs a number of different functions in order to improve its usability. The watch may, for example, allow a user to connect the watch to one or more remote electronic devices, such as an electronic performance sensor or MP3 player. The watch then displays information related to the connected electronic devices. Still further, the watch may allow a user to control the operation of one or more connected remote electronic devices. Thus, if the watch is connected to a remote speed/distance monitor employing a calibration variable, then the watch may allow the user to adjust the calibration variable.
