description In a timepiece, a seconds gear wheel mounted for rotation on a plate, and a battery and a gear train mounted on opposite sides of the seconds gear wheel. The gear train engages the seconds gear wheel and a transducer for rotating the seconds gear wheel. The seconds gear wheel has a radius smaller than a difference between a radius of the plate and a diameter of the battery. The resulting structure is very compact.
