Abstract

PURPOSE:To contrive rationalization of assembling, reduction of an intermediate bridge and effective use of a space inside a watch, by arranging a setting wheel train on the upper surface of a base plate. CONSTITUTION:A setting wheel train comprising an hour wheel 21, a minute wheel 27, a setting wheel 28 and the like is arranged between a base plate 32 and a wheel train bridge 33, on the side of a front wheel train from a rotor 26 to a minute wheel 22. Further the hour wheel 21 of the setting wheel train is put upon the minute wheel 22 and a fourth wheel 24 of the front wheel train with the same rotary center, and the minute wheel 27 of the setting wheel train is constituted by a third wheel 23 of the front wheel train with the same rotary center in their overlap. In addition, a crown wheel 29 engaging with the setting wheel 28 of the setting wheel train is settled rotatably over the surface of the base plate 32 such that a winding stem pinion 30c engages with a crown teeth 29a of the crown wheel 29 with an operation of a winding stem. Thereby, the conventional intermediate bridge 7 is not required, further it is possible to thin the watch body, along with realization of low cost due to a reduction of parts.
