Abstract (en)
[origin: EP2124111A1] The mechanism has a sprung balance (2) that is provided in regulating organ and mounted on the surface of a platform. The platform has an unbalance portion that is rotated with respect to a plate (1) such that the platform is also rotated with respect to the plate based on terrestrial gravitation. A wheelwork has a driving kinematical chain that is provided to connect an escape wheel (3) arranged on the platform to a barrel portion of a time piece for controlling movement and speed of the platform with respect to the plate.
