BALANCE HAVING INERTIA ADJUSTMENT USING AN INSERT

摘要

The method involves equipping a balance (1) and/or an insert (7) of elastic maintaining units (10) arranged to allow insertion of the insert into a housing (8) in an insertion position in which the maintaining units are under stress and to prohibit extraction of the insert out of the housing in a maintaining position in which the maintaining units are released. The insert is inserted into the housing by binding the maintaining units in the insertion position, and the maintaining units are released in the maintaining position after full insertion of the insert into the housing. An independent claim is also included for a timepiece incorporating a hairspring or a balance.
