Vibrator for mechanical clock movement

摘要

To solve the conventional drawbacks. A vibrator for adjusting a mechanical timepiece movement, wherein the vibrator 1 includes an escape wheel 5 and a first resonator 3 constituting a time reference of the vibrator 1. The first resonator 3 includes a mass element 32 that is maintained to be oscillated by at least two oscillating elements 31, and the mass element 32 maintains the oscillation of the first resonator 3. And includes at least one ankle portion 4 integrated with the mass element 32 and configured to cooperate directly with the escape wheel 5 for moving the escape wheel 5 with alternating swings. The resonator 3 further includes a base 2 that is set to be fixed or movable in the timepiece movement, and the mass element 32 is supported only by the base 2 via the vibration element 31.
