Abstract: To provide a hand motion irregularity suppressed timepiece whose 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 center wheel and the center wheel is prevented.

It is swivelled by its periphery with the help of at least three rollers, each pivoted on a ball bearing, and the barrel (3) is pivoted within the ratchet by means of a ball bearing (23). This design enables reducing to a minimum the energy losses due to friction.
