Abstract (en)
The watch has a switch board (2) actuated between two stable states for generating an electrical signal. A state controlling circuit (6) applies a control signal to an input of a frequency selector circuit (8) based on the electrical signal. The selector circuit, in response to the control signal, selects one of a set of frequencies available at an output of a frequency generator circuit. An acoustic transducer (12) emits acoustic signals according to the frequencies based on the medium such as water or air, in which the watch is found.
