This is a hybrid watch that switches from the lithium battery to solar power generation when the solar panel on the dial is exposed to 40 watts or more of sunlight or electric light, extending the life of the lithium battery. (*This is not a function to charge and store the electricity generated by solar power.) It automatically receives radio waves and corrects the time between 1:00 AM and 3:00 AM every day. (*If the radio wave reception is poor, such as inside a reinforced concrete building or during rainy weather, it functions as a built-in quartz watch.) The second time display function allows you to check the time difference, which is useful for global activities. In addition, the countdown timer function, EL backlight, stopwatch, lap time, alarm function, and calendar function allow you to use it in a wide range of situations, from business to sports. The LCD display uses a sharp, inverted LCD, which is integrated with the black case, and the contrast with the belt makes the large case more modern and enhances its unique presence.
