FIELD: watchmaking.
SUBSTANCE: present invention relates to a watchwork for mechanical watches. Essence: watchwork (500), containing a trigger mechanism (200) and a resonator (100), comprising an inertial element (2), exposed to a flexible universal joint (3) and interacting with one wheel from a set (4) of anchor wheels rotating around the main axis (D), which contains a driving means (40) interacting with an additional driving means (20) of the inertial element (2) at each angular position of the inertial element, while the flexible universal joint (3) facilitates the return of the specified additional means (20) to the main axis (D) and contains elastic return elements near the axes orthogonal to the main axis (D) (31, 32), limiting by two degrees of freedom of rotation the mobility of the inertial element (2) around the fixed position of the center of inertia (G) of the inertial element (2) relative to the board (1).
EFFECT: improvement of the watchwork by providing a relationship between the isochronous resonator and the trigger mechanism of the watchwork, eliminating the friction inherent in conventional hinges, as well as eliminating the intermittent movement inherent in a traditional trigger mechanism, which improves the quality factor and efficiency of the resonator.
