PURPOSE:To allow an oscillatory body to oscillator excellently all the time without any influence on the setting angle of a timepiece body by supportingly suspending an oscillatory driving base plate through the timepiece body in such a way that it faces perpendicularly all the time. CONSTITUTION:The oscillatory driving base plate 10 is supportingly suspended through the knife edge 18a of the timepiece body 18 to face perpendicularly all the time without reference to an inclination of the body 18 at the setting angle. Therefore, the oscillatory body 12 which is supported by the knife edge 10a of the base plate 10 and oscillates through the driving coil 16 of the base plate 10 and its own magnet 14 oscillates centering the perpendicular direction all the time. Consequently, the oscillator body of the timepiece is put in invariably excellent oscillatory pendulum motion without reference of the setting angle of the timepiece body. |
