Our newly developed electronic diver's watch with an analog depth meter (Cal.5810) displays the depth of water not by liquid crystal as previously done, but indicates the time, the present depth, and the maximum depth which are essential for diving, all by hands. This diver's watch is characterized by a high degree of visibility of the functional depth indicator hands, and the present and maximum depths can be easily read at angles of these hands in usual familiar time sense. The orange-colored depth indicator hands are located in the center of the dial, together with the mainly green-colored hour, minute, and second hands, and unit, one minute corresponds to one meter in depth. This watch can provide divers the dive time and the dive depth means of the angles and color of the hands in a new manner.
