Abstract textTo provide a timepiece having a mainspring winding state display apparatus constituted to be able to arrange a rotational center of a winding mark hand at an arbitrary pertinent position in a movement of a timepiece. A movement is provided with a barrel complete, and a speed reducing mechanism cooperatively moved with a barrel gear for reducing a speed of rotation of the barrel gear, that is, a planetary unit. A segment gear is provided to be rotatable based on an output of the planetary unit. A winding mark indicator is rotated based on operation of the segment gear. A mainspring winding state display member displays a state of winding a mainspring based on rotation of the winding mark indicator. |
