Abstract
The watch striking mechanism (1) includes at least one gong (11) fixed to a gong-carrier (12) and at least one hammer (2) for activating the vibration of the gong. The striking mechanism includes a first magnetic element (20) in the form of a moving micro-magnet, which is arranged on a striking portion of the hammer, and a second magnetic element (21) in the form of a fixed micro-magnet, which is arranged in one part of the gong. The second magnetic element is at least partly opposite the first magnetic element and is capable of generating a magnetic field of opposite polarity to the magnetic field of the first magnetic element. In a striking mode, said hammer may be driven in the direction of the gong to activate the vibration of said gong via a magnetic impulse due to the repulsion force of the two magnetic elements.
