FIELD: watches and other time measuring instruments.
SUBSTANCE: invention relates to wrist or pocket watch containing clock mechanism. Mechanical clock mechanism (100) comprises an energy storage device configured to drive a gear, the output movable component of which is rotatable about a central axis and comprising rotary resonator (10). Resonator comprises a central movable component (1) configured to turn about the central axis (A) and comprising an input movable component (2). Resonator (10) comprises a plurality of inertia elements (3), each of which is made with possibility of rotation relative to central movable component (1) around secondary axis (B), perpendicular to central axis (A), and returns to rest position relative to central movable component (1) by means of resilient return element (4), wherein each secondary axis (B) passes through the centre of mass of inertial element (3) connected to it.
EFFECT: elimination of friction in hinges and jerky movement of trigger mechanism in order to increase quality factor of resonator and efficiency of trigger mechanism, increase in service life and increase of stroke accuracy.
