A dial including: a rotating body which is provided to be rotatable; and a dial main body which includes a covering section that covers a peripheral portion of the rotating body.

A control device (2) for controlling power supply to a continuous-rotation motor, of the horological, DC type, is arranged to generate electrical pulses with a lower supply voltage to drive the rotor. The number of pulses per time interval is a function of the load applied to the motor. A voltage divider is arranged to supply the lower supply voltage with a plurality of different values and thus the electrical pulses with a variable voltage. A logic circuit counts the numbers of electrical pulses in successive time periods; to periodically select a voltage value, from among a plurality of different values, as a function of a counted number of electrical pulses or of a succession of counted numbers of electrical pulses; and to control the voltage divider so that the latter supplies the lower supply voltage with the selected voltage value after the selection of this voltage value.

An analog electronic watch includes a hand and a control unit. The hand is configured to be rotatable. The control unit fast-forwards the hand to perform a fast-forward operation in different ways according to whether a type of a display object after switching is a time type or a period type, in a case where display contents are switched by using the hand.

A satellite radio wave receiving device includes: a receiver that receives a satellite radio wave to identify a reception signal; and a processor that acquires primary date and time information from the identified reception signal and outputs a date and time notifying signal indicating date and time based on the primary date and time information to an outside of the satellite radio wave receiving device. The date and time notifying signal includes at least a timing notifying signal indicating a predetermined timing. The processor determines the predetermined timing without consideration of a timing of a second synchronization point which is a leading edge of every second in the date and time based on the primary date and time information, and outputs the timing notifying signal at the predetermined timing.

An electronic timepiece includes: a latch unit that latches and outputs specification data designating a specification in accordance with a latch signal; a signal output unit that outputs one of a plurality of driving signals including driving pulses at different periods based on the specification data output from the latch unit; a driving unit that drives a motor based on the driving signal output from the signal output unit; and a control unit that generates the latch signal so that the latch signal has at least an active level at a timing before generation of each driving pulse in the driving signal with a shortest period of the driving pulse among the plurality of driving signals.

The present disclosure relates to a signal processing apparatus and method that enables to reduce required power. In the signal processing apparatus, a RTC of a main chip and a RTC of a power supply chip are synchronized before power supply of the main chip is stopped, and the RTC of the main chip is synchronized with the time of the RTC of the power supply chip after the power supply of the main chip is restored. In this way, the RTC uses continuous time information before and after the stop. The present disclosure is capable of being applied to, for example, a GPS module in which a digital circuit includes a plurality of chips.
