This is achieved by a patented musical mechanism. A pinned disc acts on the 15 metal teeth of the comb. A metallic glass membrane amplifies the frequencies needed to emit the tune as well as guaranteeing water resistance. To improve the sound and clarity LA MUSICALE is fitted with the first magnetic strike governor in the history of watchmaking. This patented system is able to avoid background noise as well as the characteristic whirring typical of classic strike-governors.
