A timepiece movement includes a movement case, a drive mechanism, a time mechanism driven by the drive mechanism, a day mechanism, and a day adjustment mechanism. The day mechanism is driven by the time mechanism through a frictional engagement therebetween. Once a torque generated by the day adjustment mechanism overcomes the frictional engagement, the day mechanism is permitted to be driven by the day adjustment mechanism. Therefore, an indicated day of the timepiece movement can be adjusted without pulling out of a day adjustment knob or an actuating shaft of the day adjustment mechanism.
