PURPOSE:To prevent a gap from being formed between a dial and a case panel cover and a module from having a play at the time of hand correction by correcting or inputting hands by the rotation of a rotary bezel. CONSTITUTION:The rotary bezel 3 is pressed in to engage an internal gear 13 with a hand correcting wheel 14 and rotated in this state, so that the internal gear 13 rotates the hand correcting wheel 14 according to the rotation of the bezel. Further, the rotation is transmitted to a timer hand gear 24b through a switch gear 25a and a timer hand 2a mounted on a timer hand shaft 24 is moved. When the rotary bezel 3 is freed from the hand, the internal gear 13 and hand correcting wheel 14 leave each other with the repulsive force of a spring 10 and from the moment, no load is placed on the hand correcting wheel 14 from the internal gear 13 of the rotary bezel 3, so that a timer starts. |
