W W 1. Y our W atch World Time Eco-Drive Radio Controlled Watch <Radio Signal Reception Function> This watch is a radio controlled watch, which receives the standard time radio waves that are broadcast from radio wave transmitters in four regions, Japan, the USA, Europe (Germany) and China, and uses these waves to automatically correct the ti[...]

10 11 Important Points Regarding Radio Wave Reception There are two methods to receive radio signals during normal operation, Automatic and On Demand. The internal unidirectional antenna may be weakened by geography or building structures, which may require the user to place the watch near a window. When receiving radio waves: * Remove the watch fr[...]
