A device (12) for assembling and adjusting a balance spring, comprising a base (14) joined to a balance bridge (6) with an adjustable angular orientation, and comprising a bearing surface (40) and a bearing plate (42) adjacent to the bearing surface (40), both defining a service position of the end turn (8) of the balance spring (1). A first arm (20) extends from the base (14) and bears a locking member (52) for the end turn (8), said locking member (52) being designed to keep the latter in abutment against the bearing surface (40). The device (12) comprises a second arm (22) that extends from the base (14) and bears a shoe (78) that is able to be arranged at a predefined distance from the bearing surface (40) so as to cooperate with the end turn (8). A movable control member (84) is able to act on the second arm (22) in order to deform it elastically and move the shoe (78) with respect to the base (14) in order to free the end turn (8). |
