Abstract: A dive computer provides not only a digital, but also a graphic display of depth for a safety stop and a decompression stop, thereby providing a safe diving watch enabling prompting of a diver for simple maintenance of depth. The dive computer includes a timekeeping section for keeping the diving time, a measuring section for measuring diving information, a calculating section for processing diving information obtained from the measuring section, and a display for displaying diving information obtained from the calculating section. The display minimally has a first function display for displaying the current depth of the diver and a second function display for graphically displaying information giving an instruction for safety operations.
