The solar-powered function, which does not emit unnecessary batteries, has been certified by the Japan Environment Association as an "Eco-Mark" product (an environmental protection type product) for protecting the global environment. This is a world-standard radio clock that displays the time accurately by receiving two radio waves from Japan, China, Germany and the United States. The solar-powered function eliminates the need for periodic battery replacement, making it eco-friendly and economical to use for a long time. The chronograph, alarm, calendar and other useful daily functions are displayed digitally. The watch is durable and easy to put on and take off, with a tri-fold adjustable band and 10 ATM water resistance.
