Claims

[Claims for Utility Model Registration] (1) A small basic module, which forms a set of pointer display type timepieces by a second module arranged in a position where the main parts of the basic module do not overlap with each other in a plane, The pointer portion of the pointer display type timepiece is disposed near the outer circumferential portion of the basic module on the opposite side of the outer circumferential portion where the winding stem is provided, and is engaged with the first number wheel of the basic module. rotation transmission between a first air transmission wheel that rotates at the same speed and a second wheel that is disposed in the pointer section of the pointer display type timepiece and that rotates a pointer wheel that is concentrically arranged via an intermediate wheel. A pointer display type multi-hand watch characterized by an intermediate wheel interposed in the route. (2) A small basic module, which forms a set of pointer display timepieces with a second module placed in a position where the main parts thereof do not overlap in plane, and the pointer section of the pointer display timepiece. is disposed near the outer circumferential portion of the basic module on the opposite side to the outer circumferential portion where the winding stem is provided, and is engaged with the first wheel of the basic module to rotate at the same speed. The air transmission wheel has a pinion part, and the cross-sectional structure of the intermediate wheel, which together with the pinion part constitutes a reduction gear train, has pinion parts above and below the gear part, and two systems each from the upper and lower pinion parts. A pointer display type multi-hand watch, characterized by comprising a reduction gear train.
