Function consisting of an acoustic sound, obtained by a striking work made up of two hammers (s.) striking gongs (s.) at set hours, quarter- and half-hours. Some devices can emit a chime (with three or even four hammers and gongs). By a slide (s.) or an additional pusher (s.) it is possible to exclude the sonnerie device and to select a so-called grande sonnerie.

A type of minute repeater that like a tower clock sounds the time not at the will of the wearer, but rather automatically.

Sonnerie is French for "making sound" or "ring". The term generally applies to bell towers and/or bells in mechanical clocks or watches (see for example grande sonnerie), but can equally be used, for example, for the sound produced by a telephone.
