Abstract

The fixing element (1) is used to secure the outer end of a spiral balance spring and has a transverse hole (3) into which the end of the balance spring is fitted. The bottom end of the fixing element (1) has a curved outer face (2) and a slot (5) running perpendicular to the axis of the transverse hole (3), between the latter and the curved outer face (2). The transverse hole (3) pref. has a circular cross-section and the perpendicular slot (5) extends slightly beyond the hole (3) and has a flat base, or a curved base. The curved outer face (2) of the fixing element (1) is pref. coaxial to the cylindrical transverse hole (3). A lump of glue is placed in the slot (5) to secure the end of the spiral spring.
