Timepiece movement for rotating e.g. civil time hour hand, has time equation lever mounted to pivot on toothed wheels in off-centered position, and spring arranged on wheels to recall free end of lever against core

摘要

The movement has a correction mechanism including a blocking unit formed of dual-spring (120), locking clip (121) and T-shaped small lever (124) to block and release an hour wheel (113) when stop force and force are respectively applied on a control lever. A pivoted lever (103), toothed sector (105) and mobiles (107, 109) connect a profile of a time equation lever (115) to toothed wheels (111, 112). The time equation lever is mounted to pivot on the toothed wheels in buckled position. A spring (123) is arranged on the toothed wheels to recall a free end of the lever against a core (119).
