Abstract
A device for indicating a physical quantity such as depth in water by means of a pointer moving around a numbered face, using a C-MOS type computer for sampling the physical quantity at regular intervals and calculating the increment between the preceding value and the last value of the physical quantity. A pulse motor drives the pointer as many steps as are required for reaching the position at which the pointer indicates the last value of the physical quantity. The use of a sampling system and a pulse motor renders the device small enough so that it can be incorporated in a wrist watch.
