FIELD: watches and other time measuring instruments.

SUBSTANCE: invention relates to adjusting devices for clocks. Adjusting device includes inertial balance (7) including a balance axis that has the capability of rotation when mounted in a clock, balance bridge (9) and bearing (11) supported by the balance bridge and configured to hold one end of the balance axis, balance spring (1) including an inner end permanently connected to the balance and outer end (1a) integrally connected to spacer (3; 103) and spacer mounting mechanism (3; 103) including casing (17), in which the spacer is arranged and which is formed in spacer holder (5), rotating on balance bridge (9), further, the fastening mechanism includes elastic arm (15; 115) configured to rotate concentrically in respect to the balance axis between a first position, in which elastic arm secures spacer (3; 103), and a second position in which the elastic arm is disengaged from the spacer.

EFFECT: technical result consists in providing the possibility of adjusting the position of the spacer relative to the balance bridge and secure it without using a screw.
