Abstract:
An electronic diving watch comprising a sealed housing containing a clock movement which is surmounted by a dial, the watch comprising at least first graduations, said clock movement comprising electronic circuits which are able to produce time signals intended for motor means which control respectively at least a first and a second analog display organs, said display organs being disposed above the dial in order to display the current time in a first time operating mode, the watch comprising furthermore a pressure sensor which is able to produce electrical signals which are representative of the surrounding pressure and to supply said signals to said electronic circuits, the diving watch having at least a second operating mode, or diving mode, in which a display of data relating to the practise of diving is provided, wherein said first graduations serve in particular for indicating a depth, wherein said electronic circuits comprise first means which are able to control the first display organ, in said diving mode, in order to indicate the depth in conjunction with said first graduations and, wherein said electronic circuits likewise comprise second means which are able to define almost continually a minimum depth which is not to be exceeded by a wearer of the watch during the ascent from a dive, calculated from a substantially continuous decompression algorithm, and to control said second display organ in order to indicate said depth which is not to be exceeded in conjunction with said first graduations substantially in real time.
