Abstract

PURPOSE:To confine the increase of the thickness of a watch by performing a dispersion arrangement of the block such as a surface train wheel block, an electronic circuit block, an electromechanical converter block, a time correction mechanism block and the like on a main plate, and laying a coin type lithium battery thereon. CONSTITUTION:A train wheel consists of a fifth wheel 55, a fourth wheel 57 and a third wheel 59 are arranged approximately on the central part of the main plate 5 made of a synthetic resin material, said train wheel being supported with a train wheel bridge 67. Further, a flexible printed board 81 arranged with electric parts such as tuning fork type crystal vibrator 19, an IC chip 83, chip type capacitors 85 and 87 and the like, a step motor 13 and an indicating time correction mechanism 9 are dispersively arranged on each different plane space outside the wheel gears 55, 57 and 59. A coil type lithium battery 17 is placed thereon.
