Abstract (en)
[origin: EP2735920A2] The timepiece movement has a gear wheel (2), an intermediate pinion (4), a mobile intermediate wheel (5), pinion gears (6), a wheel (7), a coaxial friction wheel (8), a lower crown wheel (9) and an interdependent wheel (10) rotating a hollow sphere (1) around a rotational axis (60). A mobile pinion (12) and a mobile gear wheel (13) rotate cages, a shaft and an exit wheel of the sphere independent of a bearing, a base (29), arches (30), a top part, an upper stage of the sphere around the rotational axis. The rotational axis is tilted relative to a plane of the movement. An independent claim is also included for a clock element.
