How does a radio-controlled watch/clock work?
* Standard radio wave transmitting stations are located in Germany, the United Kingdom, the United States, China and Japan. Which country's standard radio waves your radio-controlled watch/clock can tune into vary with the specifications of each product. For more information, please refer to the instruction manual that came with your radio-controlled watch/clock.
