Abstract
A timepiece having a mainspring, an output wheel that is rotated by torque output from the mainspring, a lever that pivots synchronously to the output wheel, and a pressure member that pushes the lever. The pressure member pushed the lever so that the output torque of the output wheel increases as the mainspring unwinds.
