1,082,412. Clocks and watches. FABRIQUES D'ASSORTIMENTS REUNIES. Jan. 10, 1966 [Jan. 11, 1965], No. 1041/66. Heading G3T. [Also in Division F2] A time piece collet comprises a cylindrical body 1 provided with a central bore, the central bore providing a first cylindrical surface 4 adapted to engage a balance staff and a second cylindrical surface which defines a housing 5 to receive one end portion of a balance spring, the collet being slotted along its entire length and between its central bore and outer peripheral wall. Passageways 7 are provided in the collet for receiving the end portion of the balance spring. The first cylindrical surface 4 may be divided into two parts which are positioned one each side of the second cylindrical surface defining the housing 5, Fig. 6 (not shown).
