Abstract (en)
[origin: EP1605322A2] The mode has a hairspring collet (4) made axially free and integrated radially to a staff balance (5). The collet and the staff balance include plates interacting with each other, such that the collet radially drives the staff balance and vice versa. The position of the collet on the staff balance is defined by rigidity of the balance.
