Abstract

The device includes a gear differential, a connection between a central moving body and the spindle of the drum. A second central moving body and the barrel of the drum are connected. In the differential, a satellite system is mounted on a satellite carrier and worked by the meshing of the external cogs of the central moving body. One of the connections is a direct plug and the other has a gear with a moving connection reducer/multiplier, with two cogs. The satellite system also has at least one moving reducer/multiplier. ADVANTAGE - Mechanism indicates state of wind of watch spring.
