Grande Sonnerie

Some complication watches offer a function known as the grande sonnerie. A watch with a grande sonnerie function requires two gear trains, one to operate the hands and one to manage the striking system.

This function consists of a striking mechanism that automatically sounds the hours and the quarter hours as well as being able to sound on demand.

By pushing a button the sound can be repeated, and some watches have movements able to even repeat the minutes on demand.
