ABSTRACT:
The present invention has as an object the provision of an electromechanical analogic display device for electronic chronometers, comprising at least an electromagnetic motor controlled by an electrical impulse of short duration. The attractive influence of the latter distorts a spring, very rapidly storing the produced energy to release it in the form of kinetic energy and driving a toothed wheel coupled to the analogic display while on the other hand this electromagnetic motor activates a locking system permitting the passage of a single tooth per cycle, and thus assures for said device immunity from mechanical shocks and most particularly from tangential accelerations.
