PURPOSE:To mass-produce parts by using a time display train wheel, time correcting mechanism, and timepiece base plate to be incorporated in a movement in common with an analog mechanical timepiece and an electronic timepiece. CONSTITUTION:While the movement barrel of the mechanical timepiece is substituted by the battery 42 of the electronic timepiece, a speed governor such as a bulb support 6 is substituted by a stepping motor 10 and other train wheel mechanisms are used in common. An elastic part 40 is provided at a part of return arm and a conduction pin 41 is provided to a circuit substrate 8 to use the time correcting mechanism in common with the mechanical timepiece and electronic timepiece. Further, a main plate 1 is used in common with both mechanical timepieces and electronic timepiece, and a train wheel is supported by a support 2 for the mechanical timepiece and by the circuit substrate 8 for the electronic timepiece. |
