The advantages of radio receiver watches are obvious: without ever having to be adjusted, they always display the right time and automatically switch between summer and winter time. The time generated by the atomic clocks is sent to a transmitter. In Germany there is such a transmitter in Mainflingen near Frankfurt, in Great Britain there is one in Rugby. The Mainflingen transmitter reaches receiver watches within a radius of up to 1,500 km, depending on the model. A particular feature of many CASIO receiver watches is that you can use the signals from both transmitters
