Constant force escapement mechanism for a timepiece with indirect seconds

摘要

The constant force arrangement has a mechanism for indirect seconds suitable for an intermediate seconds drive (14) driven by a seconds wheel (9) and an indirect seconds wheel (15) and a tensioning module (4-8), a cam (2), an armature (11) and a stop wheel (13). The stop wheel of the constant force arrangement is arranged on the intermediate seconds drive of the indirect seconds mechanism. An independent claim is also included for the following: (a) a clock mechanism for a clock, especially a wristwatch, with an indirect seconds mechanism.
