Abstract
A clock or watch movement has a spindle assembly which includes an escape wheel, a pinion and a common spindle. The escape wheel is driven by a balance wheel and a driven wheel of the movement meshes with the pinion. The ends of the spindle are journalled in bearings which are adapted to permit relative movement of the spindle assembly radially of the axis of rotation of the driven wheel of the movement. A biasing spring urges the spindle assembly in the direction towards said axis.
