    The present invention provided a hand motion irregularity suppressed timepiece whose assembling ability has been improved. As to a spring having a flat portion and a bent portion, the flat portion is disposed between a second chronograph wheel and a center wheel, and the bent portion is sandwiched and supported under a pressurized state by a train wheel bridge and a bottom plate. By this, the spring portion prevents a hand motion irregularity of the second chronograph wheel by the fact that the second chronograph wheel is pressure-contacted with the train wheel bridge. Further, by forming a gap between the second chronograph wheel and the center wheel, an accompanying rotation between the second chronograph wheel and the center wheel is prevented.
