PURPOSE:To realize an electronic watch for diving, in which a battery is not used up during diving, even when the display functions of the time and diving recording data are added. CONSTITUTION:Time information, diving recording data, etc., are displayed on a liquid-crystal display unit 3 in an electronic watch for diving, thus resulting in comparatively large power consumption. However, an auxiliary generating system 6 generating power by driving by a turbine 62 rotated by an air current from a compressed air bomb 7 is also incorporated in a watch body 10 in addition to a normal main generating system 5, thus allowing charging during diving. |
