<p>PURPOSE: To provide a display mechanism in a clock having a time display device for displaying two different times on both surfaces of a body with a simple structure, thin the thickness of the body itself as much as possible, and minimize the backlash generated by a gear train moving pointers on both the surfaces. CONSTITUTION: A pointer provided on one side is arranged to one of character surfaces of a mechanism, and rotated by a gear train having a central gear 12 (second gear) fixed to a central shaft 13 having a pinion. The pointer provided on the other side is driven by the other gear train, and the gear of the gear train is mounted on the central shaft 13 of the central gear (second gear). A gear body 10 can be wound by an automatic winding device having an oscillating weight 7. A time setting stem having a neutral axial position and two drawing potions is cooperated with a transmitting mechanism to correct the display of one display device in one drawing position and correct the display of the other display device in the other drawing position.</p> |
