Abstract (en)
[origin: EP2367078A1] The watch (1) has a watch case including a bottom (5) fixed to a middle (4) in a sealing and removable manner, and a glass (2) closing the watch case in a sealed manner. A watch movement (20) is maintained at interior of the watch case and provided with a striking mechanism activated in determined periods to produce a sound. An acoustic membrane (10) is connected to the watch case to radiate the sound produced by the striking mechanism to the outer side of the watch case, where the acoustic membrane is made of amorphous metal.
