ABSTRACT:
A timepiece has a mainspring winding state display apparatus for arranging a rotational center of a winding mark hand at an arbitrary pertinent position in a movement of the timeplace. The movement has a barrel complete and a speed reducing mechanism cooperatively moved with a barrel gear of the barrel complete for reducing a speed of ratotion of the barrel gear. A segment gear undergoes rotation in accordance with an output of the barrel gear. A winding mark indicator undergoes rotation in accordance with an operation of the segment gear. A mainspring winding state display member displays a winding state of the mainspring in accordance with rotation of the winding mark indicator. The segment gear includes a first segment gear for receiving an output of the speed reducing mechanism and a second segment gear for rotating the winding mark display wheel.
