<P>PROBLEM TO BE SOLVED: To provide a mechanical modular unit which guarantees accuracy of an operation parameter, and which can be assembled at a low production cost. <P>SOLUTION: Functional modules for a mechanical clock are provided that respectively comprise a sub-assembly, which carries components for a particular timepiece function for converting a movement between an input wheel set 3 and an output wheel set 4. A pre-adjusted module 1, which includes adjustment and/or assembly components to be irreversibly secured after performing an adjustment and a check of the particular timepiece function with respect to a single sub-assembly on a test bench, and which is constituted by transforming the sub-assembly by irreversibly securing the adjustment components, comprises: at least one bearing surface 5; and locating means 6 for recognizing and positioning the module 1 relative to another element of a mechanical modular unit 100 or a plate by the abutment of a first bearing surface 5 on a complementary bearing surface included in the other element or the plate. <P>COPYRIGHT: (C)2013,JPO&INPIT |
