A Pocket or wristwatch fitted with a ringing-mechanism that is automatically released at a defined time striking a gong, bells or a solid surface to produce sound or vibrations
Made by companies such as Blancpain, Jaeger LeCoutre, Seiko and Vulcain.
One characteristic of all alarm watches and sonneries in general, is the requirement for all the screws to be tightened far more than on conventional time pieces to avoid the excessive vibrations literally shaking the watched apart.
