Abstract

PURPOSE:To reduce the errors of an alarm function and simplify the operation relating an alarm function by correcting train wheel, a timing counter or an alarm memory simultaneously by an external operation part. CONSTITUTION:A sliding pinion 64 is engaged with the 2nd setting wheel 66 by pulling up a winding stem 1 by one stage, and a star transmission gear 67 engaged with the 2nd setting wheel 66, the 2nd star wheel 73 fixed on the same shaft of the star transmission wheel 67 and an unlocking transmission wheel 74 are rotated by rotating a winding crown. The unlocking wheel 75 is indexed by an unlocking index lever 76 at the rate of one click per 10min. A piezo- electric switch lever 70 is released once per click and an alarm hand rotates 10min. A hand correcting mechanism connecting to the 1st setting wheel 57 can be driven by pulling up the winding crown by 2 stages. A timing counter and an alarm memory can be corrected simultaneously by the output signal of the piezo-electric switch lever 70.
