Claims (1)

[Scope of Claim for Utility Model Registration] An hour hand wheel that rotates once every 12 hours in conjunction with a clock train; a reference setting wheel that is arranged coaxially with the hour hand wheel and is capable of setting an arbitrary reference time; and the hour hand wheel. a guideline cam coaxially disposed between the guideline setting wheel so as to be rotatable and slidable in the axial direction; a biasing spring for urging the guideline cam toward the guideline setting wheel; and the guideline setting wheel. a guideline adjustment wheel that is directly engaged with the guideline adjustment wheel and can adjust the guideline setting time; a hand setting wheel that is arranged coaxially with the guideline adjustment wheel and is capable of adjusting the hour and minute hands; and an operable guideline adjustment knob that is press-fitted into the guideline adjustment wheel. a needle setting knob that is press-fitted into the needle setting wheel and is operable; and an elastic body that presses and biases the needle setting knob in the axial direction, and the pressing force of the elastic body is greater than the output torque. A timepiece correcting mechanism, characterized in that it generates static torque that is smaller than a given load and greater than the torque that does not rotate the hand setting wheel during reference adjustment.
