Claims

[Scope of utility model registration request]

A predetermined cycle T ₁ after receiving power supply from a commercial power source clock data output means for generating a clock clock and outputting clock data based on the clock cycle of the clock clock; and a clock data output means for generating a clock clock having a cycle _T2 shorter than the cycle _T1 by receiving power from the commercial power supply. a timing data output means for synchronizing the phase of the timing clock with the phase of the clock, and outputting timing data based on the clock period of the phase-synchronized timing clock, and the power supply of the commercial power source being cut off. 1. A timepiece device comprising: a backup power supply section that supplies backup power only to the timepiece data output means.
