摘要： A watch includes a chargeable power supply, a crystal oscillation circuit including a crystal oscillator and an oscillation circuit and configured to stop oscillating when a power supply voltage falls below an oscillation stop voltage and to start oscillating when the power supply voltage exceeds an oscillation start voltage, which is higher than the oscillation stop voltage, and a divider circuit that outputs a reference signal by dividing an oscillation signal output from the oscillation circuit. The watch also includes a temperature compensation circuit that performs a temperature compensation function operation that compensates for variation of the reference signal due to a temperature, a first voltage detection circuit that detects that the power supply voltage exceeded a first voltage that is set higher than the oscillation start voltage, and a control circuit that starts the temperature compensation function operation of the temperature compensation circuit when the first voltage detection circuit detects that the power supply voltage exceeded the first voltage, and subsequently continues the temperature compensation function operation even when the power supply voltage falls below the first voltage.

摘要： A wiring substrate at which a metal wire is formed includes a substrate containing a resin as a main component and an organic substance having a hydroxyl group; and a metal plating layer constituting the metal wire. A formation portion of the metal wire at one surface of the substrate is rougher than a non-formation portion of the metal wire at the one surface of the substrate, and has the organic substance in a state of being embedded in the resin, and a catalyst. The wiring substrate with such a configuration can increase the adhesion of the metal wire to the substrate.

摘要： A timepiece includes an arithmetic circuit, a first switch that controls connection of a temperature compensation table storage to a power supply circuit, and a second switch that controls connection of a device-difference compensation data storage to the power supply circuit. The arithmetic circuit calculates a compensation amount based on a temperature measured by a temperature detector, a temperature compensation data, a device-difference compensation data, and outputs to a frequency adjustment control circuit and a theoretical regulation circuit. The first switch is controlled to the connect state during a first power supply connection period including a temperature compensation data read period. The second switch is controlled to the connect state during a second power supply connection period including a device-difference compensation data read period.
