A timepiece, in which an indicating hand is driven by a motor and high speed processing is required for driving a load other than the indicating hand, includes a main control circuit that instructs drive timing of the motor so as to drive the load, and that is operated by an operation frequency serving as a first frequency, and a motor control unit that generates a drive pulse for driving the motor, and that is operated by an operation frequency serving as a second frequency which is lower than the first frequency.

A timepiece movement includes a control unit that determines a position of an indicating hand by detecting a rotation state of a rotor, and a train wheel that transmits a drive force of a stepping motor to the indicating hand, and that has a first gear, and a second gear and a third gear which mesh with the first gear. The first gear has a reference load unit that causes fluctuations in a load applied to the rotor in each case of meshing with the second gear and the third gear. A first line segment which connects a center of the first gear and a center of the second gear to each other forms an angle smaller than 180 with a second line segment which connects the center of the first gear and a center of the third gear.

An electronic watch includes a display surface, a magnetic sensor including a first detection axis and a second detection axis orthogonal to the first detection axis, with the first detection axis and the second detection axis being disposed in a plane parallel to the display surface, a correction unit configured to correct an error due to an offset magnetic field included in a detection value of the magnetic sensor, a calculation unit configured to calculate a bearing and magnetic intensity, based on a value acquired by correcting the detection value by the correction unit, and a display unit configured to cause the display surface to display the bearing and the magnetic intensity that are calculated by the calculation unit to be displayed.

An electronic watch includes a pointer, a receiver (GPS receiver) configured to receive positional identification information for identifying a current location, a magnetic sensor, and a controller configured to acquire destination information indicating a position of a destination, identify a direction of the destination, based on the positional identification information, an output of the magnetic sensor, and the destination information, identify a distance to the destination, based on the positional identification information and the destination information, and display a direction of the destination with the pointer. The controller switches the pointer to a set hand movement operation when the identified distance a threshold value.

Provided is an electronic timepiece capable of suppressing variation in the drive speed of a rotor, and driving a motor at a constant speed. The electronic timepiece has a driver; a controller that controls the driver to the on state or the off state according to a current flowing through a coil of a motor; a detection signal output device configured to output a detection signal when the on time or the off time, which are the continuous time of the on state and off state of the driver, meets a specific condition; a reference signal output device that outputs a reference signal used as a reference of a drive speed of the motor; and a drive cycle adjuster that compares the output timing of the detection signal and the reference signal, shortens the drive cycle when the detection signal is output after the reference signal, and when the detection signal is output before the reference signal, lengthens the drive cycle of the motor.

An electronic timepiece includes: a main unit having a reporting unit that reports information to a user; a crown that can be pulled out from and pushed back into a main unit by the user; a sensor that detects a state of the electronic timepiece; and a processor, wherein the processor detects a state of the crown and the state detected by the sensor and switches between a plurality of modes in accordance with the state of the crown, and wherein upon detecting that the crown has been pulled out or pushed back in, the processor causes the electronic timepiece to operate in a state reporting mode in which the reporting unit reports the state detected by the sensor to the user.

A drive device includes a plurality of motors; and a motor control processing unit that drives the motors. When the motor control processing unit drives the plurality of motors, it performs control such that a driving speed of one motor of the plurality of motors decreases and driving of the other motor of the plurality of motors starts.
